What does this PR do?
Seems that BLIP2
keep_in_fp32_moduleswas not picking up correctly until 36722 (thus no errors up to today). Now that thequery_tokensare actually kept in 32, we are getting dtype mismatch error in inference. (reported by @hmellor)This PR fixes by casting inputs to correct dtypes, and keeping
qformerinfp32as well. The fix was tested with slow BLIP-2 tests and vLLM tests
