_pickle.UnpicklingError: invalid load key, '<'.

[fly-dragon211]

When I run the code "run_exp_tab1.sh", I meet the error:
Traceback (most recent call last): File "eval_retrieval.py", line 226, in <module> main() File "eval_retrieval.py", line 84, in main cfg = configdataset(dataset, os.path.join(get_data_root(), 'test')) File "/data2/user/my_code/Attack/cnnimageretrieval-pytorch/cirtorch/datasets/testdataset.py", line 16, in configdataset cfg = pickle.load(f) _pickle.UnpicklingError: invalid load key, '<'.
It seems that there are some problems with your pkl files. (gnd_rparis6k.pkl)
