Can you provide some more context: What operating system are you using? Are you following the "Build with Docker on Linux" instructions in the README, or something else?

[acoret]

im using archlinux,docker didnt work on my computer,so i have to build my self,i have follow the dockerfile to install dependency,protoc and tensorflow-cuda

The closest that I can find is haskell/c2hs#192
If you can catch the command line used to invoke c2hs (stack -v might be useful) and you also collect the inputs to c2hs, we can probably figure out if it really is this issue or not.

You could start by including c2hs version.

I also ran into this, also using Arch.
@blackgnezdo versions used: tensorflow 0.2.0.0, c2hs 0.28.6.
