OSError: [WinError 193] %1 is not a valid Win32 application

[oggyoggy448]

I am trying to run the following code with anaconda 4.7.12

from __future__ import print_function
import torch
x = torch.rand(5, 3)
print(x)

Unfortunately I'm getting the following error

Traceback (most recent call last):

lt is likely that your environment is messed up. As you can see from the traceback, there are two python environments involved here:

1. C:\Users\nouma\AppData\Roaming\Python\Python37
2. C:\Users\nouma\Anaconda3

Please make sure your PATH is clean and you can actually remove one of them first.

I'd removed all the numpy libraries and installed everything from the beginning and that solution worked for me.

Still not working!

I am having this kind of problem in django!
Can anybody could solve this or have similar kind of problem.

@sthabinod Well, it means that at least one dependency in the DLL load chain is not a valid one. You may get some better idea if you debug with Process Monitor or the Debugging Tools for Windows.

I uninstall python and anaconda and reinstall it again but same error.

@Mubashir-alam You have multiple Python installations.
C:\Users\P.C.S\anaconda3
C:\Users\P.C.S\AppData\Roaming\Python\Python38
And I guess the second one is 32-bit, not 64-bit. That's why it throws this error.
