Sample Validation Failure

[24367452]

Sample Validation Failure
I have successfully installed AIHWKIT via pip install aihwkit but when I run the following example :

from torch import Tensor
from aihwkit.nn import AnalogLinear

model = AnalogLinear(2, 2)
model(Tensor([[0.1, 0.2], [0.3, 0.4]]))

But there was an error :

What's the reason for this?

Hello, can you guide me on how to resolve this? @maljoras

[ShiJLdot]

I have the same problem，have you solved it？

[24367452]

I haven't solved it yet. If you have already solved this problem, please let me know and I will be very grateful!

我有同样的问题，你解决了吗？

[ShiJLdot]

I tried Linux system instead and it works

Hello @24367452, can you give more info on what OS and versions of Python you are using to run this script?
@ShiJLdot is saying that Linux is working but I'm not sure if that is a problem with the OS or how the package is installed.

If this is in Windows, are you using the python shell or WSL? The best way and less error-prone to do it is through WSL.

[PabloCarmona]

We are closing this issue as it seems to be a problem of the user OS and can be solved using WSL in the case of Windows and using pip instead of conda for OSX systems. We planned a new bundle version to be compatible with OSX in conda-forge here #676.

If you have any new concerns or problems @24367452 let us know in a new issue or reopen this. Thank you so much for working on the project and if we can help you with anything more don't hesitate to let us know! :)
