Hello,I'm running your project and an error occured:

Traceback (most recent call last):
File "/home/PycharmProjects/gymdemo/mobile_robot_rl/run.py", line 71, in

File "/home/PycharmProjects/gymdemo/mobile_robot_rl/run.py", line 15, in run_vision_env
length=history_length)
File "/home/PycharmProjects/gymdemo/mobile_robot_rl/common/env_wrapper.py", line 150, in make_env
env = FrameStack(env, length, nchw_format)
File "/home/PycharmProjects/gymdemo/mobile_robot_rl/common/env_wrapper.py", line 104, in init
value.shape = generate_shape(shp)
AttributeError: can't set attribute

Do you know how to solve it？

Thanks in advance :)
