CompileRequest too large

[Naveen Swamy]

Hello XLA Devs,

I have an issue where the CompileRequest failed because of the xla message > 2GB. Upon further inspection, I found that the HLOModule Proto is the one that is large due to the tensors that are used as constants being sent across. 

I dumped the hlo proto and zipped the file and it is comparatively very small.

I am guessing someone here must have encountered this else we are doing something wrong by adding the constant tensors in the HLO proto. 

If you encountered a similar situation, how did you handle this?

Additionally,

1) Is there a compile pass that I can run to remove constants ?

2) or send tensors in a binary format?

Thanks, Naveen
