Server(bwapi) crashes immediately after launching torchcraft-py

[yiyang92]

On client side I have a following message:
ZMQ:server::connect(): invalid message

Also protocol version must be changed as TorchCraft now using v17 instead of v16
bwapi errors file:

I also got the same problem，“ZMQ_server::connect(): invalid message”， and then bwapi crashed。

Looks like it's because of protocol incompatibility. Current TorchCraft server uses FlatBuffers as a serialization backend.

The mentioned error is thrown by the server logic. It's context implies that received message was not parsed successfully. If we look here we'll see that TorchCraft-py simply tries to write the text message to the ZMQ socket.

P.S.: I'm using TorchCraft-py as an reference for my pending Rust API. Looks like I need to switch to the original code.

To add a little more detail, torchcraft-py using torchcraft protocol version 16, but since torchcraft v1.1 the version of the protocol has been updated to version 17 (which is the one using flatbuffers).

Ideally, torchcraft-py would be updated to support torchcraft protocol version 17. For now you can get torchcraft-py working by using an older version of torchcraft. I replaced the BWEnv.dll in the docker image I was using with version v1.0-2 and attack_weakest.py seemed to work.

Edit: removed misconception about poor performance
