ValueError: operands could not be broadcast together with remapped shapes [original->remapped]: (1,158) and requested shape (1,160)
please help.. any hints are welcome..
length of obs returned me 160, so i assume req shape is (1,160)
I see that
obs_space = env.observation_space
returns a space size of (158)
