Device-side assertions’ error when speculative decoding with different length of prompts.

[ECHO]

I am running the speculative sampling task with the ‘compile’ mode of the generate.py script. The original speculative decoding version of gpt-fast decodes one prompt several times, but I want to decode different prompts. I have observed that when I decode with prompts of different lengths, I encounter an ‘enable device-side assertions’ error. The following are the error messages:
