Hi, great article once again,
I am trying to predict using trained models but get the same error in both single and multi stock scenarios. When I run prediction:
trade = data_split(processed_full, '2019-01-01','2021-01-01') e_trade_gym = StockTradingEnv(df = trade, turbulence_threshold = 332, **env_kwargs) df_account_value, df_actions = DRLAgent.DRL_prediction(model=model_sac, environment = e_trade_gym)
the code above gives this error ValueError: Length mismatch: Expected axis has 0 elements, new values have 1 elements
the error happens in this location: ~\Anaconda3\envs\py36\lib\site-packages\finrl\model\models.py in DRL_prediction(model, environment) 78 action, _states = model.predict(test_obs) 79 account_memory = test_env.env_method(method_name="save_asset_memory") ---> 80 actions_memory = test_env.env_method(method_name="save_action_memory") 81 test_obs, rewards, dones, info = test_env.step(action) 82 if dones[0]:
I am using Jupyter notebook downloaded as of Feb 9, 2021, something must have changed in the modules since you ran it Thanks Vadim
