[WIP] Add an in-process CompilerGymService for python backends #727
Conversation
This adds a new class, `compiler_gym.spaces.ActionSpace`, that wraps
the existing `env.action_space` types, and provides a pair of methods
`to_string()` and `from_string()` for serializing and deserializing
to/from string, respectively. This replaces the old
`CompilerEnv.commandline()` method, which has been marked deprecated
and will be removed in a future release.
To update your code, replace:
env.commandline()
With:
env.action_space.to_string(env.actions)
And replace:
env.actions_from_commandline("...")
With:
env.action_space.from_string("...")
The reason for this change is that "command line" is a specialized
term that does not make sense for all compiler environments. The new
ActionSpace class also provides default implementations of `to_string()`
and `from_string()`, so there is no need to implement these two
methods when providing a new backend. As a result, the LoopToolEnv
class has been removed.
This was deprecated in v0.2.1.
Remove a handful of things that were deprecated several releases back.

A new
CompilerEnvimplementation that doesn't use gRPC but instantiates and calls methods onCompilationSessiondirectly.Work-in-progress, there will be bugs.
