I run this:
train(start_date = '2022-08-25',
end_date = '2022-08-31',
ticker_list = ticker_list,
data_source = 'alpaca',
time_interval= '1Min',
technical_indicator_list= INDICATORS,
drl_lib='elegantrl',
env=env,
model_name='ppo',
if_vix=True,
API_KEY = API_KEY,
API_SECRET = API_SECRET,
API_BASE_URL = API_BASE_URL,
erl_params=ERL_PARAMS,
cwd='./papertrading_erl', #current_working_dir
break_step=1e5)

And got error.
