Can you tell me the output of:

import platform
print(platform.machine())

Can you also attach the "system_info.txt" file generated by this script?

python tools/get_system_info.py

[gMan1990]

Python 3.7.7 (tags/v3.7.7:d7c567b08f, Mar 10 2020, 10:41:24) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import platform
>>> platform.machine()
'AMD64'
>>>

Can you also attach the "system_info.txt" file generated by this script?

python tools/get_system_info.py

[gMan1990]

@workhorsy

1. system_info.txt
2. append Traceback, see comment-1

[workhorsy]

It looks like platform.machine is returning invalid results for you. In both cpuinfo.py and the get_system_info.py platform.machine should be returning something like "AMD64". Instead it is returning "" or None. Do you know why this would be changed on your machine?

[workhorsy]

Did this solve your problem? Or do you need more help?

[gMan1990]

@workhorsy ok, I maybe know this problem.

1. install python in windows (and pip, py-cpuinfo)
   • add python to PATH
2. install cygwin in windows
   • install python37-pip in cygwin (and py-cpuinfo)
   • install openssh in cygwin
3. open cygwin and run /usr/sbin/sshd
4. connect it with ssh

6. but one is Count: 48 and another is Count: 64, I only have 48 counts.

[workhorsy]

The wrong CPU core count looks like a duplicate of #90 .
