`ray` throwing `TypeError: can't pickle ...` on provided VM

[jonathanloganmoran]

Hello,

With the VM Ubuntu setup provided by Udacity, there is an issue running download_process.py with the ray.remote() decorator. I am receiving the following error:

TypeError: can't pickle google.protobuf.pyext._message.MessageDescriptor objects

which is called inside /data/virtual_envs/sdc-c1-gpu-augment/lib/python3.7/site-packages/ray/cloudpickle/cloudpickle_fast.py by ray_remote.

More info

• Python version: 3.7.3;
• ray version: 0.8.7;
