E NameError: name 'FROZEN_SYM_BD' is not defined

[dbl001]

I am on MacOS 13.1 with an Anaconda virtual environmen: decision-transformer-gym

Where is FROZEN_SYM_BD defined?

E.g. - $vi +5 conf/conf_cfgs.py

MetaCfg = FROZEN_SYM_BD['fairdiplomacy.MetaCfg']

Quick note: Since you mentioned MacOS, my guess is you don't have an NVIDIA GPU and hence no CUDA, which is required for this repo. We're using Ubuntu 20.04.4 LTS, so I suggest moving to cloud (e.g. v100s or p100s on AWS) if you want to play around with this repo.

Correct. I was trying to get the code to work with ‘MPS’. Bad idea?

What's MPS?

‘MPS’ is Apple’s Metal Performace Shader API. ‘MPS’ is Apple’s replacement for CUDA on M1, M2, AMD, ...

FROZEN_SYM_BD is a global defined in the conf/*_pb2.py files that is produced by the hacky protobuf patching system that runs on top of the protobuf compilter that should get run when you make. It's some global dictionary that the autogenerated protobuf python code puts stuff into.

Part of the output from grep FROZEN_SYM conf/conf_pb2.py -C 10 | less:

Relevant code here:
https://github.com/facebookresearch/diplomacy_cicero/blob/main/heyhi/bin/patch_protos.py

which gets run as part of this command:
https://github.com/facebookresearch/diplomacy_cicero/blob/main/Makefile#L23

and which hacks the compiled protobuf files produced by protobuf to extend the functionality of the python protobuf objects (this is why the readme recommends a particular version conda install --yes go protobuf=3.19.1) and to define "frozen" i.e. immutable versions of them as well.
