Proteins longer than 1024 causes an exception on the CPU and poisons the GPU

[konstin]

Bug description

Having a sequence longer than 1022 residues causes the an unspecific exception on CPU and GPU. On the CPU, it says IndexError: index out of range in self. On the Quadro RTX 8000 I tested, it causes a CUDA error: device-side assert triggered that will cause all further attempts to embed sequences of any length to fail with the same error.

I'm aware that esm was trained with sequences of less than 1024 amino acids; I'm opening this issue because this does not seem to be mentioned in the repo nor the paper, and from the error message in the exception it's hard to figure out what is wrong. I'd also be interested in how you'd suggest handling user input with longer sequences: Should this simply error with a message that this is not supported or do you suggest another way of handling this (I've seen https://github.com/facebookresearch/esm/issues/21#issuecomment-763217386 listing some strategies)?

Reproduction steps

Pretty much the readme example, only with a longe sequence added:

Expected behavior

Either a way to handle long sequences, or an error message that explains the length limit, ideally with a note in the readme. That error also really shouldn't poison the GPU in ways that I need to restart the process before I can do any proper computation again, but not sure if you can do anything about it or if that's an issue with torch and/or cuda

hi @konstin , sorry for late reply and thanks for flagging. Yes actually I noticed this is an issue also within fairseq with learned positional embeddings, depending on pytorch version you'll get those gnarly error messages or something that's easier to pinpoint. Let us look at putting some check there

[tomsercu]

We put a check in place now; actually the full answer is quite subtle:

• The esm-1 models have SinusoidalPositionalEmbeddings and could be used with longer sequences, they just haven't been trained that way so it's tricky/dangerous to assume generalization to those.
• ESM-1b (see updated appendix of Rives et al. 2019) found that learned embeddings are better; meaning each of the 1024 postiions has its unique learned embedding. This fundamentally can not deal with longer sequences. But performance is better; see also many recent transformer papers in other domains.

Let us know if that makes sense!
