KeyError: 0

[qwertyuu]

While trying out this tool for the first time, by installing via pip install ds4ml, I tried a dataset we use at work in CSV format and I got this error running either data-pattern or data-synthesize

<__array_function__ internals>:5: RuntimeWarning: Converting input from bool to <class 'numpy.uint8'> for compatibility.
Traceback (most recent call last):
  File "/[redacted]/venv/lib/python3.8/site-packages/pandas/core/indexes/range.py", line 385, in get_loc
    return self._range.index(new_key)
ValueError: 0 is not in range

The above exception was the direct cause of the following exception:

Sadly, as you may know, I cannot provide you with the data I used to produce this error.

Please let me know if I can help you debug this, I would really like this to work!
