RuntimeWarning: overflow encountered in ubyte_scalars in smb_env.py:149 #98

Closed Neqit closed 4 years ago

Describe the bug

During learning process, program keep spamming this message:

C:\Users\User\anaconda3\envs\mario\lib\site-packages\gym_super_mario_bros\smb_env.py:151: RuntimeWarning: overflow encountered in ubyte_scalars return (self.ram[0x86] - self.ram[0x071c]) % 256

Expected behavior

Message about overflow encountered in ubyte_scalars should't spam

Screenshots

here is the screenshot with condition of spam: image

and here is the meaning of the other numbers in smb_env.py image

Additional context

Tried to check if variables self.ram[0x86] and self.ram[0x071c], or their subtraction, become > 255. but didn't find anything strange. The only thing that i noticed, that this message keeps spamming only if I use DDQN algorithm instead of basic DQN
