Having trouble getting run_CLTrain.sh to execute

I’m having trouble getting the run_CLTrain.sh script to execute.
1. Where to get 'file_name="data/data_simcse/${train_file}_for_simcse.csv'?
2. I would appreciate some guidance on recommended parameters for training, such as the number of epochs to use, etc.
3. Currently, I downloaded the ‘nli_for_simcse.csv’ from 'https://huggingface.co/datasets/princeton-nlp/datasets-for-simcse/resolve/main/nltasets-for-simcse/resolve/main/nli_for_simcse.csv', I encountered an error with the following line of code: (src/train.py, line 319)
`examples[sent0_cname][idx] = conv_dict(ast.literal_eval(examples[sent0_cname][idx].replace('−inf', '−2e308')))`
The error occurs when trying to parse the string with ast.literal_eval.

I would appreciate your help!!!
