Hi @DanielLikeU , Let us know if you are still facing this error. Can we know the repro steps, so that we can repro it from our end

I've been looking into errors with dbprophet for a few hours and this seems quite common. It seems to error installing dependencies (pystan on Windows is the one I'm struggling with for different reasons). Maybe check the version of numpty your installing or one suggestion was to add dbprophet twice. You'll find these on the fbprophet github issues.

I'm having a similar issue deploying prophet to Azure. My import libs as follows.

import json
import logging
import numpy as np
import pandas as pd
from prophet import Prophet
import azure.functions as func

I've removed versions from requirements.txt for these libs as follows
pystan
numpy
pandas
prophet

No errors building and running locally. Using python3.9. Set python to 3.7 via az cli, still fails to deploy.

Errors seen when deploying to Azure.
