GNU radio companion does not start

Hmmm. If it's saying that it cannot import gnuradio, then it must have a problem with the Python path. Conda is usually pretty good about making that work in a variety of situations, but you may have some other installation of Python that is interfering. Stick to the Conda prompt and see if you can figure out how deep the problem runs. This is what I see trying the following commands:

(base) C:\Users\rvolz>where python
C:\Users\rvolz\radioconda\python.exe
C:\Users\rvolz\AppData\Local\Microsoft\WindowsApps\python.exe

(base) C:\Users\rvolz>echo %PYTHONPATH%
%PYTHONPATH%

Key results are that the radioconda python.exe comes first, and %PYTHONPATH% is unset so that nothing is overriding the default.

I never ran python on that computer; hence, there was no python installation prior to that of Radioconda.
That's what I see when trying to type the commands you suggested:
(base) C:\Users\ernst.otto>where python
C:\Users\ernst.otto\AppData\Local\conda1\python.exe
C:\Users\ernst.otto\AppData\Local\Microsoft\WindowsApps\python.exe

[ottomc2]

it does not seem to like % after PYTHONPATH
also, echo -command is not recognized
the location of .exe file looks correct otherwise?

Oh, the echo %PYTHONPATH% line is meant to be executed from the Conda prompt and not within the Python interpreter.

the location of .exe file looks correct otherwise?

Yeah, that looks good. And running python launches the correct conda-forge version. I'm stumped.

After launching the Python interpreter (python.exe), can you report what the following code returns?

import sys
print(sys.path)

[ottomc2]

OK i opened a Conda prompt window and typed echo %PYTHONPATH% there:
(base) C:\Users\ernst.otto>echo %PYTHONPATH%
%PYTHONPATH%

Then, after launching python.exe

import sys
print(sys.path)
['', 'C:\Users\ernst.otto\AppData\Local\conda1\python310.zip', 'C:\Users\ernst.otto\AppData\Local\conda1\DLLs', 'C:\Users\ernst.otto\AppData\Local\conda1\lib', 'C:\Users\ernst.otto\AppData\Local\conda1', 'C:\Users\ernst.otto\AppData\Local\conda1\lib\site-packages', 'C:\Users\ernst.otto\AppData\Local\conda1\lib\site-packages\win32', 'C:\Users\ernst.otto\AppData\Local\conda1\lib\site-packages\win32\lib', 'C:\Users\ernst.otto\AppData\Local\conda1\lib\site-packages\Pythonwin']

[ryanvolz]

Thanks. My installation reports essentially the same, but without the last 3 entries (\win32, \win32\lib, \Pythonwin). Since they come at the end and the other ones look right, I don't think they would have any effect. But it's still curious to me.

You said import gnuradio errored. How about some other things, like import math and import numpy?

[ottomc2]

import math :
on Conda prompt directly
(base) C:\Users\ernst.otto>import math
'import' is not recognized as an internal or external command,
operable program or batch file.
after launching python.exe :

import math

[ottomc2]

this interface does not like >

[ottomc2]

hence, my text looks weird when i type >>> in the beginning.
there is no responce on import math; it just returns: >>>
that's it

[ryanvolz]

So the standard library package built into Python (math) works, but not an external package (numpy). I don't know what that tells us and will have to think about it for a little bit.
