TCP remote connection fails if optimizer_path is not given

[Maik93]

Hi, I'm trying to connect to a remote TCP server that runs the compiled solver. As exposed here: https://github.com/alphaville/optimization-engine/blob/d655a88295ea786a8f788f851b589ae2c5c68a7b/open-codegen/opengen/tcp/optimizer_tcp_manager.py#L37-L39

I've written mng = og.tcp.OptimizerTcpManager(ip="127.0.0.1", port=8333) but this throws KeyError: 'build' on line https://github.com/alphaville/optimization-engine/blob/d655a88295ea786a8f788f851b589ae2c5c68a7b/open-codegen/opengen/tcp/optimizer_tcp_manager.py#L69

It's trivial that only if optimizer_path is not None the variable self.__optimizer_details is correctly populated (through the call self.__load_tcp_details(), I suppose), but if optimizer_path is not given, there is simply https://github.com/alphaville/optimization-engine/blob/d655a88295ea786a8f788f851b589ae2c5c68a7b/open-codegen/opengen/tcp/optimizer_tcp_manager.py#L65

It's clear that it is a dictionary with no build key, but I don't know how to fix it, so here I am to write this report ;)

Have a good job and a nice day!

Thanks @Maik93 for reporting this. I reproduced the issue and fixed the issue locally. I'll release an updated version of opengen and I'll ping you.

The issue is solved in opengen version 0.6.3 (just released).
