The same. Have you resolved this issue?

Have a try. "nextstate, reward, done, , _ = env.step(action)" for five values to unpack

I tried. But new errors may arise, "ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (2,) + inhomogeneous part."

chage all the code "state = env.reset()" to "state, _ = env.reset()"
