Example code from Hugging Face website not working (Infomer)

I am trying minimal example code of Informer specified on HuggingFace website: Informer
however I am getting this error while running that:

  File "C:\Users\User\anaconda3\lib\site-packages\torch\nn\modules\linear.py", line 114, in forward
    return F.linear(input, self.weight, self.bias)

RuntimeError: mat1 and mat2 shapes cannot be multiplied (1536x23 and 22x32)

Any ideas what could be wrong?
