How to find out the bit python 32 or 64

Everything is very simple here, we put the Python interpreter in accordance with the “religion” of UNIX. What is the discharge of the operational system, we put this and Python.

For example, if the Linux system costs 64-bit, then Python select 64-bit. Similarly, if you have a 32-bit Linux system, respectively, Python will put 32-bit.

How to find out what is the bit of the operational system in Linux using the ubuntu example:

You can find out the bit of the Linux ubuntu OS in various ways. I will give two most common methods that do not require installation of additional software:

Both teams work and display similar information. After the launch of any of them in the terminal window, the discharge of the operating system will be displayed:

How to determine if my Python shell works in a 32-bit or 64-bit mode in OS X?

I need a way to say in what mode the shell is inside the shell.

I tried to view the platform module, but it seems that he only tells you about the bit architecture and the layout format used for the executable file “: the binary file is compiled as 64-bit, although (I work for OS X 10.6), therefore, he seems to always report about 64-bit, even if I use the methods described here to include a 32-bit mode).

Updated: one of the ways is to look at SYS.MaxSize as here:

SYS.MaxSize was presented in Python 2.6. If you need a test for older systems, this slightly more complex test should work at all Python 2 and 3 releases:

By the way, you may have a desire to use Platform.Architecture for this. Unfortunately, its results are not always reliable, especially in the case of universal binary files OS X.

find, system, computer, hardware

When starting the Python interpreter in the terminal / command line, you can also see a line like:

Python 2.7.2 (Default, Jun 12 2011, 14:24:46) [MSC V.1500 64 bit (AMD64)] on win32

Where [msc v.1500 64 bit (AMD64)] means 64-bit python. Works for my specific setup.

Make Python.VV on command line. I must return the version.

For non.gram solution, look in the activity monitor. He lists the architecture of 64-bit processes as “Intel (64-bit)”.

Platform architecture is not a reliable way. Instead of us:

Mostly the version of the response of Matthew Marshall (with a structure from STD.Library):

Note. In Mac OS X (and, possibly, on other platforms), executable files can be universal files with several architects.

To get the “64-bit” of the current interpreter, it is more reliable to request an SYS attribute.MaxSize:

In my Centos Linux system, I did the following:

1) launched the Python interpreter (I use 2.6.6) 2) launched the following code:

3.5.1 (V3.5.1: 37a07ce5969, December 6, 2015, 01:54:25) [MSC V.1900 64 bits (AMD64)]

Try using CTYPES to get the size of an empty pointer:

It will be 4 for 32 bits or 8 for 64 bits.

Struct.Calcsize (“P”) returns the size of the bytes necessary for storing one pointer. In a 32-bit system, he would return 4 bytes. In a 64-bit system, he would return 8 bytes.

find, system, computer, hardware

Therefore, the next will return 32. If you work with a 32-bit python, and 64. If you work with a 64-bit python:

Platform.Architecture is problematic (and expensive).

Conveniently test SYS.MaxSize 232 starting with py2.6.

This is a reliable test for the actual (default) size of the pointer and compatible at least with PY2.3: Struct.Calcsize (‘P’) 8. Also: CTYPES.SIZEOF (CTYPES.c_void_p) 8.

Notes: there may be assembly with the GCC option.MX32 or something that are applications of 64-bit architecture, but by default 32-bit pointers are used (memory and speed saving). “Sys.maxsize = ssize_t “cannot strictly represent the size of the pointer C (usually 231. 1 in any case). And there were / there are systems that have different sizes of the pointer for code and data, and it is necessary to clarify what is the purpose of determining the “32-bit or 64-bit regime?”

He must display “64-bit” or “32-bit” depending on your platform.

As an alternative (in the case of binary OS X files):

Mac OS X: How to find out that I’m in 64-bit mode?

I can’t remember how to see if my OS X (10.6) The installation works in a 32-bit or 64-bit mode.

go into information about the system and select the program in the left panel. In the right panel you will see a 64-bit nucleus and extensions. If he says yes, you are in 64-bit mode, if not, then you are in 32-bit mode.

OS X actually does not have general “modes”, as the question-developing components (T suggest. e. processes and core) can work independently in different modes. In principle, whenever OS X launches any part of the software, it looks at what architectures the software supports, what equipment you are working on, and tries to make the “best” choice in which mode to launch this particular part of the software (Macintosh performance manual has a good set of notes on how to reduce this).

If you want to know in what mode the core works, the answer of John T is true (for 10.6; In earlier versions there were only 32-bit nuclei). Please note that while 10.6 is able to run the nucleus in 64-bit on many Mac models, it only actually does this by default on the latter Mac Pro and XSERves, and AIUI even then only under the server version of OS X.

If, on the other hand, you want to know if OS X can run applications in 64-bit mode, then Arjan’s answer is correct for 10.5, and for 10.6 (but not for 10.4, which can only run Pure-Posix programs in 64-bit). Please note that this is mainly controlled by the computer processor: Core Solo and Core Duos only 32-bit, while the Core 2 Duos and Xeons are capable of 64-bit. There are no problems with the launch of applications in 64-bit mode under a 32-bit nucleus (or vice versa).

Finally, if you want to know if a specific program works in 64-bit mode, the activity monitor will show you under 10.5 and 10.6 (I don’t know about 10.four).

I will take this opportunity to recommend a series of Prince McClin’s “Road to Mac OS X Snow Leopard” in Appleinsider: ’64 Bits’, ’64-bit, Santa Rosa and the Great PC Fraud,’ twice the RAM, half the price, half of the price, 64-bit ‘and “Future of 64-bit applications”. They were written up to 10.6 was released, but still do good work on covering the consequences of various combinations 32. and 64-bit operating mode.

for 10.6, the answer of John T Rights. Just for those who come here with the same question for 10.5: Find the chess program in Finder, click with the right mouse button, get information. You will see the option of returning to a 32-bit version, if 10.5 can work in 64-bit mode:

How to check the technical characteristics of Mac?

If you want to check the technical characteristics of the Mac, the processor of which generation is installed and what is the amount of RAM? Today we will tell you how to do it.

Data on the technical characteristics of Mac may be needed if you are going to install a new application or game, and you want to know if it is compatible with your laptop. Or you decided to sell Mac and want to provide potential customers with reliable information about the device. In any case, following our simple hints, you can find all the information of interest about the technical characteristics of the Mac.

How to see the technical characteristics of Mac

  • Press the apple icon in the upper left corner of the screen.
  • From the drop.down menu, select the first item: About this Mac.
  • There will be a message in which all the information of interest will be, including the type of processor, the size of the memory and characteristics of the video card.
  • Immediately, you can consider in detail the state of memory, choosing a storage point in the upper row.

How to check which processor on Mac

This Mac gives some information about the processor, but does not specify the processor of which generation is on the gadget. Processors of different generations, even if both have 3.2Hz will have different performance.

To find out the processor of which generation is on the Mac, you need to know the following information: what type of processor is worth (Core i5, Core i7, Xeon) and when the laptop was released.

We go to the EVERY MAC website and, according to the above information, find a link to the generation of the processor that Apple was used in the production of Mac.

Forewarned is forearmed

Apple always cares about its users. This is not just a beautiful advertising slogan, it is the official policy of the company. Therefore, after the release of MacOS High Sierra, users began to receive notifications about the incompatibility of 32-bit applications with future versions of MacOS.

What does it mean? That’s right: that you need to update the application. Unless, of course, the developer has already released a 64-bit version. If not, it’s time to look for analogues. Because after the release of MacOS Catalina this application will not work.

Users with access to the beta version of “Catalins”, by the way, can confirm my words. After updating the operating system, many of them received a notification with a list of 32-bit programs that are no longer supported. You will receive the same beautiful list and you, if you do not go to more modern.

How to find outdated 32-bit applications?

Find out the discharge of the application is very Press the Apple icon in the upper left corner of the screen.2. Choosing the item “About this Mac”.3. We go to the section “Information about the system”.four. We scroll the list on the left side of the screen down to the “soft” section.5. Click on “Programs”.

Everything is in front of us is a complete list of all applications installed on this computer. We are looking for the column “64 bits”, we look at what is written there. If yes, then everything is great, after the release of MacOS Catalina, the program will be available. If “no”, then it needs to be updated.

The easiest way to do this is through Mac App Store. There is a section “Updates”, which falls all notifications of new versions on. If the App Store does not know when a new assembly of the application under 64 bits appears, you can contact the developers directly. Or switch to software from competitors, the benefit of every popular project now has a “double”. And in 8 cases out of 10 it is no worse than an obsolete 32-bit “original”.

How to disable Mac program checks?

Prepare an ISO-image with the Windows installer (you can download the image on Microsoft). Launch the Boot Camp Assistant from the utility folder (use SpotLight for quick access) and select the following points: Create a Windows installation disk and insert an empty USB drive. Install Windows 8 or New.

How to install macos mojave on a virtual machine

First we decide on the application used. You can choose any popular solution: VMware, Virtualbox or Parallels.

In this example, we will use the Parallels Desktop utility, in other programs, the installation process will be similar.

Now you need to download the right version of macos. Cupertinists kindly hid the old versions of MacOS and they cannot be found through the search at the Mac App Store.

Fortunately, you can use direct links: download macos 10.14 Mojave or MacOS 10.13 High Sierra.

We launch the application for creating a virtual machine and through the file menu. new create a new system.

Select the item install Windows or other OS with DVD or from the image.

Confirm the installation from the loaded image of MacOS or manually indicate the path to the installer.

We confirm the release of the required place on the disk under the image of the system.

We make the usual installation and setting of MacOS in the virtual machine window.

After installation in the virtual machine settings, do not forget to provide access to the network and computer equipment. If necessary, you should change the resources provided by the virtual machine (operational and video memory).

And at the very end we provide access to all disks or selected folders on Mac to quickly copy data between the main system and virtual.

Restart the virtual machine to enter into force.

All! Now you can install and use old 32-bit applications.

At the moment, this is the most convenient way to use the necessary programs and games, the support of which has disappeared in MacOS Catalina.

How to find out Mac OS 64 or 32?

Apple TV running Mac OS X Leopard!

Line 64-bit nucleus and extensions will indicate yes. If you use a 64-bit nucleus and not. If you work 32-bit nucleus.

Note. Mac OS X 10.6 Snow Leopard-the last release that can run the 32-bit Intel Mac, Mac OS X 10.7 Lion and above, by default, 64-bit. In addition, the system profile has been renamed the system of the system in OS X 10.7.

This article of the knowledge base from Apple should provide you with the correct answer, as it depends on how your old MacBook Pro is.

In principle, if you have something more new than the MacBook 2008, you have a 64-bit processor and Osâ € |

Another option is to use Sysctl in the shell:

Shows 1 if the processor is able to run 64-bit programs and 0 otherwise.

macOS. How To See System Information

As you could see from all answers-Macs differ from other operating systems (OS) in that the 32-bit and 64-bit separation fishing line for a trimmer is blurred. You can run a 32-bit code on a 64-bit processor.

A good overview of this topic is on the 64-bit version of Apple the transition Guide to keep in mind that this transition was started before a tiger was released on April 29, 2005 and is still taking place.

What is 64-bit calculations?

For the purposes of this document, 64-bit calculations are defined as support for a 64-bit targeted space-support for parallel use of more than 4 GB of memory using one executable program-no more, no less.

Starting from version 10.4, Mac OS X supports the 64-bit command line executable files on Macintosh computers based on G5 and 64-bit Intel computers Macintosh.

Starting from version 10.5, Mac OS X supports full-function 64-bit applications on Intel Macintosh computers based on G5 and 64-bit.

Starting with Snow Leopard, Mac OS X uses a 64-bit core on some Intel computers.

In addition, the processor, which is “64-bit”, still has parts whose width is only 32 bits. Similarly, the processors that are “32-bit” also have parts that have 128 bits (or more) widths. That is why most people are focused on the address space for a particular program, and not on the hardware “64-bit” or on the fact that it is “64-bit”

It really does not matter until you go to a more specific issue. Why are you asking about it? I hope this general review will help you understand what people really mean when they discuss their bit.

In the terminal window, enter UNAME.m. If you get x86_64. then you use a 64-bit OS.

Go to the Apple menu and select “About this Mac”. If you have a Core Duo processor, you have a 32-bit processor. Otherwise (Core 2 Duo, Xeon, i3, i5, i7, everything else) you have a 64-bit processor.

Mac OS X is a bitter-agility, so either you need to work. If you are still in doubt, use a 32-bit version.

ARCH team without arguments displays the type of machine architecture.

Results (from the ARCH reference page (1)):

Just start the activity monitor and find the process named Kernel_Task. Then look at the View column. If he says Intel. Then you are currently using a 32-bit regime. If he says Intel (64-bit). then, as the text, you use a 64-bit regime.

Note. You must show all the processes. From the opening list TE next to the search field (filter).

Then you can check the answer @nate Bird to the processor that you have and supported modes for it.

OS X has no total 32/64-bit mode; He simply launches each program in the “best” accessible mode, based on what the processor is capable of and what the program supports. Many OS X programs are included in the universal binary format, which means that they have several versions (some combination of 32-bit PowerPC, 64-bit PowerPC processors, 32-bit and 64-bit Intel processors) included in the same file.

Eclipse does not seem to come in this way, so you need to decide which version to download. I am not familiar with him enough to know whether he needs to launch in the same mode as you, in order to debug it; If so, run your program and find it in the Activity Monitor to find out in which mode it works. If Eclipse should not be in the same mode (or Java code simply starts inside Eclipse), you can use either one (if you do not use a 32-bit processor, that is, Core Solo or Core Duo).

If it gives 1. This means that your computer has a 64-bit architecture.

Or use the Arch command. which can return either i386 (32-bit intel) or x86_64 (64-bit version of Intel).

Launch UNAME.A in the shell to show the details about the nucleus. You can see Release_x86_64 x86_64 for a 64-bit version

Open Terminal.App and run the next command:

Uname.m | IF GREP.Q 64; then echo “64-bit CPU (` uname.m`) “; Else echo” 32-bit CPU (`uname.m`) “; fi

On the command line you can start.

As already mentioned by Gordon Davisson, fat binary files can include both 32-bit and 64-bit executable program files (see. Also multiple architecture, Single Build).

How you can find out the discharge of the system?

All greeting! In today’s article, I will tell you about how to find out the discharge of the system. This question is currently relevant. In modern operating systems, 32-bit and 64-bit versions are often found. Of course, in order for the computer to work in 64-bit mode, a processor is needed that will support x64 architecture. As a rule, modern computers just support 64-bit instructions. This allows you to work as a computer, and with 32-bit operational systems, and with 64-bit systems.

In Windows Vista and Windows 7

In the start to find and click the “control panel”. Select the System tab. Find the line “Type of System” and on the contrary of this inscription see the discharge of the system. Remember that if you have a 32-bit system, then it will not be able to see all the RAM if it is more than 3 gigabytes.

In Windows XP

  • Press the “My Computer” with the right button
  • and select “Properties”.
  • Then look at the discharge of the system.

In Mac OS X

  • Click on Apple and select “About this computer“.
  • Select the item “In more detail”.
  • In “” Choose “Software”. “Software review” will allow you to see the discharge of the system.

Minute attention, friends! I suggest reading a couple of articles on how to cut the song online or how to change the password in classmates, as well as how to find out the IP of your computer.

In linux

The discharge of the system is determined by the UNAME command.A, which is introduced in the terminal. The 64-bit system is determined by the presence in the response of the value system x86_64. If there is i686, then the system is 32-bit.
