Facing an issue with preprocessing ASSISTMents 2015, please assist

[arshdeepsp]

While attempting to preprocess the data for training, I am running this command
python data_preprocess.py --dataset_name=assist2015
I have the dataset in my data file, and I get this error

Traceback (most recent call last):
File "data_preprocess.py", line 48, in
split_concept(dname, writef, args.dataset_name, configf, args.min_seq_len,args.maxlen, args.kfold)
File "/Users/arsh/miniconda3/envs/pykt/lib/python3.8/site-packages/pykt/preprocess/split_datasets.py", line 537, in main
total_df, effective_keys = read_data(fname)
File "/Users/arsh/miniconda3/envs/pykt/lib/python3.8/site-packages/pykt/preprocess/split_datasets.py", line 24, in read_data
stuid, seq_len = tmps[0], int(float(tmps[1]))
ValueError: could not convert string to float: ')'

What could I be missing, please let me know.
