Ctrl+C doesn't work as expected

[AdamStelmaszczyk]

Run the simplest:

from osim.env import ProstheticsEnv

env = ProstheticsEnv(visualize=False)
observation = env.reset()
for i in range(200):
    observation, reward, done, info = env.step(env.action_space.sample())

and try to stop it with Ctrl+C. Instead of stopping it will only print:

^C<built-in function Manager_integrate> returned a result with an error set

It seems it's a fairly general error related to error handling in python3 (and an exception thrown in OpenSim integrator) https://github.com/zulip/zulip/issues/6153 It's beyond the scope of this repo but relevant, I'll try to see if there are some workarounds.

The issue is not about a general error returned a result with an error set. It could be anything, let's say it's some RuntimeError, doesn't matter.

The issue is about handling this exception inside osim.py.

It's beyond the scope of this repo but relevant

It's within the scope of this repo. In this repo there is a Python code that calls C++. And this Python code is not handling exceptions coming from C++ well.

Good call, exceptions from the integrator were not passed.

Oh, nice, thank you Łukasz :)
