PermissionError: [WinError 5] Access is denied

[clustor]

The following program gives an error "PermissionError: [WinError 5] Access is denied" on Windows 10 running Python 3.7.2 & 3.7.7. It looks like the orca executable cannot be accessed. Interestingly, the same program runs without issues on latest Python 3.8 but unfortunately one of the modules I need pythonnet is not yet supported on 3.8. I wanted to check if there is any workaround for this issue in orca.

I wonder what difference between Python 3.8 and 3.7 could explain that failure... :thinking:

try adding stdin=subprocess.DEVNULL to the POpen() call that generated the exception.

File "C:\Users\DeletedName\AppData\Local\Programs\Python\Python37\lib\site-packages\plotly\io_orca.py", line 1146, in validate_executable executable_list + ["--help"], stdout=subprocess.PIPE, stderr=subprocess.PIPE

this may be related to the issue I created the other day. #321

I'm afraid the problem still exists even after setting stdin to subprocess.DEVNULL while calling POpen()
