Off topic suggestions

gym_anytrading, Please add this tutorial!!!

Have you modified the dizoo.gym_anytrading.envs.StocksEnv? The 'pq' needs to pass the parameter 'stocks_data_filename'='STOCKS_GOOGL' instead of "df"

There is a tutorial for gym-anytrading.

Yes, I made the changes to dizoo. gym anytrading. envs The content of the data section obtained by StocksEnv has not been modified in other locations, but even if the original 'stocks_data_file name'='STORKS_GOOGL' is used to pass parameters, this problem still occurs.

And thank you for providing the tutorial link, thank you very much!!

Sorry I can't reproduce your error because I'm not sure about your development environment. And our repo has not yet tried to adapt gym-anytrading to stable-baseline.
