Can't adapt it to newer jericho versions. No 2.1.0 version was found

Hi. I'm trying to run drrn/train.py, but can't resolve all the issues.
First of all there is no support for jericho with version 2.1.0, if I'm not mistaken. I could only see versions v1.0, 3.1.1, 3.1.2.
For this I just removed the jericho version check in train.py,
Next there is this api mismatch in env.py. For example it complains that there is no 'load_bindings' defined. I substitutited these calls with methods from FrotzEnv, but I'm getting another error related to multiprocessing from vec_env.py:
assert not _current_process._config.get('daemon'),
AssertionError: daemonic processes are not allowed to have children
