Hello.
I was interested in converting a machine learning model written in pmml, python, or R into sql code, and then I learned about sklearn2sql.
This was the service I was looking for, but when I ran it there was a problem. I think it's an error in requests.post(WS_URL, json=data) based on response[500].

Because of these problems, I couldn't finally get the sql code.

If you could tell me how to solve it, I would be very grateful. I'm still new to this field, so please understand.
thank you.
