Example execution error

[opocaj92]

Hi everyone,
I've just installed the library in a fresh Python3 virtual environment, and everything went fine. However, when I try to run the example command python3 -m gfootball.play_game --action_set=full to validate my installation, I get the following error:

Traceback (most recent call last): File "/usr/lib/python3.8/runpy.py", line 185, in _run_module_as_main mod_name, mod_spec, code = _get_module_details(mod_name, _Error) File "/usr/lib/python3.8/runpy.py", line 111, in _get_module_details __import__(pkg_name) File "/home/jacopo/PythonEnvs/marl_py38/lib/python3.8/site-packages/gfootball/__init__.py", line 17, in <module> from gfootball.env import scenario_builder File "/home/jacopo/PythonEnvs/marl_py38/lib/python3.8/site-packages/gfootball/env/__init__.py", line 21, in <module> from gfootball.env import config File "/home/jacopo/PythonEnvs/marl_py38/lib/python3.8/site-packages/gfootball/env/config.py", line 27, in <module> import gfootball_engine as libgame File "/home/jacopo/PythonEnvs/marl_py38/lib/python3.8/site-packages/gfootball_engine/__init__.py", line 43, in <module> from _gameplayfootball import * ImportError: /home/jacopo/PythonEnvs/marl_py38/lib/python3.8/site-packages/gfootball_engine/_gameplayfootball.so: undefined symbol: _ZN5boost10filesystem6detail28directory_iterator_constructERNS0_18directory_iteratorERKNS0_4pathEPNS_6system10error_codeE
How can I fix it? Anyone ever experienced it before?

Following from this, when tried to do this again from scratch (this time inside a Docker image), I get the following:

Traceback (most recent call last): File "/usr/lib/python3.8/runpy.py", line 185, in _run_module_as_main mod_name, mod_spec, code = _get_module_details(mod_name, _Error) File "/usr/lib/python3.8/runpy.py", line 111, in _get_module_details __import__(pkg_name) File "/usr/local/lib/python3.8/dist-packages/gfootball/__init__.py", line 17, in <module> from gfootball.env import scenario_builder File "/usr/local/lib/python3.8/dist-packages/gfootball/env/__init__.py", line 21, in <module> from gfootball.env import config File "/usr/local/lib/python3.8/dist-packages/gfootball/env/config.py", line 27, in <module> import gfootball_engine as libgame File "/usr/local/lib/python3.8/dist-packages/gfootball_engine/__init__.py", line 43, in <module> from _gameplayfootball import * SystemError: initialization of _gameplayfootball raised unreported exception

Anyone has any idea why this is happening?
