In code/eda.py, the main function eda starts with below in line 175

sentence = get_only_chars(sentence)

get_only_chars function performs preprocessing to remove non-alphabetic characters from text. Therefore, if you input text data consisting of only non-alphabetic characters, len(words)-1 becomes -1 in the code below in line 117 and etc. and an error occurs.

rand_int = random.randint(0, len(words)-1)

If you input text data that consists only of non-alphabetic characters, you can avoid this error by modifying the get_only_chars function in line 45, so that the data is excluded from removal as follows.

if char in 'qwertyuiopasdfghjklzxcvbnm123456789(). ':

i have same problem，big probability is your data problem. if you are sentence is null or particular token ,like "------".
check your data.

I also have this problem, could this problem refers to dataset?
because my dataset has three columns but the dataset in this repository has two columns.
would you please help me.
