I can run this scripts in the terminal but when debugging in VScode, it have error in this line: total_max_steps=int(config['simulation']['total_max_steps'])

Have you seen this problem before?

I can debug use pdb but vscode is supper powerful than pdb, which IDE you use for debug?

[matthieu637]

It seems like a problem in your config.ini. You should have a section [simulation]

with a key like

total_max_steps=X

An example of config.ini is given in the readme.

I have it in config.ini

[simulation]
total_max_steps=20000000
testing_each=20
#number of trajectories for testing
testing_trials=1

Could you try with the new commit 80c4f6669605e6ce5b876a3219fbb470e8f6b1e1. My guess it that's it can't find your config.ini ?

[huangjiancong1]

I agree that the VScode debug can't find the config.ini too. Can not solve, it seems that VScode IDE debugging is different with pdb debugging, the return of config.read(clparams[config]) VScode:

pdb:

> /home/jim/ddrl/gym/run.py(65)<module>()
-> config.read(clparams['config'])
(Pdb) p config.read
config.read         config.read_file    config.readfp
config.read_dict    config.read_string  
(Pdb) p config.read
config.read         config.read_file    config.readfp
config.read_dict    config.read_string  
(Pdb) p config.read(clparams['config'])
['config.ini']
(Pdb) 

[matthieu637]

You can specify a custom path for the config.ini by using --config while calling run.py

Fixed！
