Get CPU info with pure Python 2 & 3

Project description

Py-cpuinfo gets CPU info with pure Python. Py-cpuinfo should work without any extra programs or libraries, beyond what your OS provides. It does not require any compilation(C/C++, assembly, et cetera) to use. It works on Linux, OS X, Windows, BSD, Solaris, Cygwin, Haiku, and BeagleBone. It currently only works on X86 and some ARM CPUs.

These approaches are used for getting info:

  1. Windows Registry (Windows)
  2. /proc/cpuinfo (Linux)
  3. sysctl (OS X)
  4. dmesg (Unix/Linux)
  5. isainfo and kstat (Solaris)
  6. cpufreq-info (BeagleBone)
  7. lscpu (Unix/Linux)
  8. sysinfo (Haiku)
  9. Querying the CPUID register (Intel X86 CPUs)

Run as a library

from cpuinfo import cpuinfo # from installed with pip
#import cpuinfo # from path

# Have the library pick the best method for getting your CPU info
info = cpuinfo.get_cpu_info()

# Or use /proc/cpuinfo
#info = cpuinfo.get_cpu_info_from_proc_cpuinfo()

# Or use the Windows registry
#info = cpuinfo.get_cpu_info_from_registry()

# Or use sysctl
#info = cpuinfo.get_cpu_info_from_sysctl()

# Or use CPU CPUID register
#info = cpuinfo.get_cpu_info_from_cpuid()

# Print some CPU values
print('Vendor ID: {0}'.format(info['vendor_id']))
print('Brand: {0}'.format(info['brand']))
print('Hz Advertised: {0}'.format(info['hz_advertised']))
print('Hz Actual: {0}'.format(info['hz_actual']))
print('Hz Advertised Raw: {0}'.format(info['hz_advertised_raw']))
print('Hz Actual Raw: {0}'.format(info['hz_actual_raw']))
print('Arch: {0}'.format(info['arch']))
print('Bits: {0}'.format(info['bits']))
print('Count: {0}'.format(info['count']))
print('Flags: {0}'.format(', '.join(info['flags'])))

Bugs and Corrections

Please report a Bug if you suspect any of this information is wrong.

If py-cpuinfo does not work on your machine, run the script:

python tools/

and create bug report with the generated “system_info.txt” file.
