most probably You used the environment which returns 5 values from step method and 2 values from reset method. change this code return state, reward, done, False, dict() to return state, reward, done, dict()

and from the reset function return only state return self.get_state(price) please check the code.

it must resolve the error. from new update gymnasium returns 5 values but elegantrl still returns 4.

let me know if you still get the error.

Krish,

Hi - thanks so much for your help. I'm still struggling a little with where to locate the code you are referring to? I'm new to coding so bear with me please. I have searched for the code you referred to but can't find it in the runtime? Can you be more specific on its location? Oli

in the above-marked file. you will find the reset method it returns 2 values change it to return self.get_state(price)

same with the step method return state, reward, done, dict()
