Running the rl2 algorithm issue

[KyraGavin]

I'm sorry to bother you, but I encountered an error，

File "/mnt/data/chenjinhao/.local/lib/python3.7/site-packages/tensorflow/python/client/session.py", line 1161, in _run
    np_val = np.asarray(subfeed_val, dtype=subfeed_dtype)
ValueError: setting an array element with a sequence.

while running the original file. I didn't make any changes to the original file. Can you help me clarify this?
