Your problem is created by the linker trying to dynamically load the library. There could be several root-causes for this:

Permissions. The user should have permission to load the library, so when mounting file systems in docker, the owner id and the group id that are in the host are not necessary the same id in the container although they might be the same name.
Wrong binary format. The host OS is compiling the binary in wrong format. This can happen if you run the compile on (by example) macOS and use it in a linux container.
Wrong mounting. The mounting, by example, with noexec will also prevent the library to be loaded.
Difference in libraries from both environments. Due to the differences of the environment where the library was compiled, you might be missing some libraries, so use ldd grid_subsampling.cpython-35m-x86_64-linux-gnu.so and ldd -r -d -v grid_subsampling.cpython-35m-x86_64-linux-gnu.so check all the libraries that are linked.

I see your problem on using bytes(x). change it to x.to_bytes(1, 'big') solve your problem

Use below code to reveal what difference
