errors when running probe_classifier.py

[YuJieF]

Hello, thanks a lot for your great work. When I run probe_classifier.py. There are some errors:
File "probe_classifier.py", line 205, in
train_X, train_y, dev_X, dev_y, test_X, test_y, feat_dim, num_classes, cat2id, id2cat = load_data()
File "probe_classifier.py", line 35, in load_data
feat_jsonl = json.loads(feat_jsonl)
File "/home/fang/anaconda3/envs/probe_env/lib/python3.8/json/init.py", line 357, in loads
return _default_decoder.decode(s)
File "/home/fang/anaconda3/envs/probe_env/lib/python3.8/json/decoder.py", line 337, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/home/fang/anaconda3/envs/probe_env/lib/python3.8/json/decoder.py", line 355, in raw_decode
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

And I have no idea how to fix it.
