China_A_share_market_tushare.py cannot run correctly.

when run to
trained_ddpg = agent.train_model(
model=model_ddpg, tb_log_name="ddpg", total_timesteps=10000
)

it complains：
trained_ddpg = agent.train_model( tensorflow.python.framework.errors_impl.FailedPreconditionError: tensorboard_log/ddpg\ddpg_1 is not a directory.
How to fix it?

ps.
and another fix is in env_stocktrading_China_A_shares.py
def _get_date(self):
if len(self.df.tic.unique()) > 1:
'''
wrong code , date -->time

date = self.data.date.unique()[0]
'''should be'''
date = self.data.time.unique()[0]
