Compression fails on non-contigous feats

[janvainer]

Hi, I am getting a stride error when running compression on non-contiguous tensors:

lilcom: compression error: last stride should be 1, got 253

The error message is a bit confusing and its not clear wht the problem is. Some solutions could be:

1. warn the user that inputs should be contiguous and make the tensor contiguous or
2. fail with a message that will tell the user to make their tensor contiguous.

Does this error still exist?

It's intended to be a warning that the user should make the tensor contiguous.
