Biencoder with GPU RuntimeError: Expected object of device type cuda but got device type cpu for argument #3 'index' in call to _th_index_select

Hi, thanks for your code! When I set the no_cuda in biencoder_wiki_large.json as True, then I run python blink/run_benchmark.py, it returns an error, please see below, is there anything that I missed? Best regards, A.

I have the same problem. Have you found the solution?

Not solved yet. Maybe inference with biencoder was just designed to run with CPU - it was around 1 hour with the pre-computed entity embeddings.
