Thanks for the code snippet.  
Since it’s not reproducible with the last code, could you try to use:

```python
x= F.max_pool1d(x.transpose(1,2).contiguous(), kernel_size=x.size()[1])

```

and rerun the script, please?

Also, which PyTorch version are you using?  
Make sure to update to the latest stable release, as `Variables` are deprecated since `0.4`.
