Why DoubleDQN output action always be 9 #28

Open georgezouq opened 6 years ago

georgezouq commented 6 years ago

I test DoubleDQN algorithm find from 2012-01-01 to 2018-01-01 Model output action always be 9 (Buy 601398). Is it possible 6 years just keep buying one stock??

By the way, I change default stock_codes list

From
stock_codes = ["600036", "601328", "601998", "601398"]
To
stock_codes = ["600036", "601328", "601398", "601998"]

But the output action still be 9...

Some output:
