SLM Lab As a Python Pip Module

[Wen-Wen-Luffy]

Describe the bug
Can not implement a Session in an external project using the code in the gitbook.

To Reproduce

1. OS and environment: MacOS
2. SLM Lab git SHA (run git rev-parse HEAD to get it):
3. spec file used: slm_lab/spec/benchmark/ppo/ppo_cartpole.json

Additional context
I replace "from slm_lab.env import OpenAIEnv" to "from slm_lab.env import make_env" line 5
"from slm_lab.experiment.monitor import Body" to "from slm_lab.agent import Body" line 7
"self.env = OpenAIEnv(self.spec)" to "self.env = make_env(self.spec)" line 17
Because previous components can not be found.

Error logs

Traceback (most recent call last):
  File "pipex.py", line 56, in <module>
    sess = Session(spec)
  File "pipex.py", line 18, in __init__
    body = Body(self.env, self.spec['agent'])
  File "/Users/shiwanyin/SLM-Lab/slm_lab/agent/__init__.py", line 113, in __init__
    self.init_tb()
  File "/Users/shiwanyin/SLM-Lab/slm_lab/agent/__init__.py", line 132, in init_tb
    log_prepath = self.spec['meta']['log_prepath']
TypeError: list indices must be integers or slices, not str

Hi @Wen-Wen-Luffy thanks for spotting this. The code snippet was a bit old. I have updated it to the latest version that is runnable. Please check the page again. Thanks!
