JSON Decode Error when loading MiDas

[michaeltan53]

Hi, when I was running the command of evaluate.py, train_mono.py and sanity_hub.py, I recieved an error like this:

Traceback (most recent call last):
File "sanity_hub.py", line 40, in

raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Can someone help me to solve it? Many thanks.
