No module named using virtual environment in VS Code

Environment data

VS Code version: 1.19.0 Python Extension version: 0.2.3 Python Version: 3.6.3 OS and version: Windows 10 x64 bit

I am trying to run python app that runs on a virtual environment perfectly with no issues. When i copy this code to run in VS Code as azure function i get the following error:

from fbprophet import Prophet\r\nModuleNotFoundError: No module named ‘fbprophet’\r\n",“errorDetails”:"Microsoft.Azure.WebJobs.Host.FunctionInvocationException : Exception while executing function: Functions.MLLoaderInsight

I am expecting to run this app in VS Code with no issues as i run it on IPython on the same machine using the same virtual environment.

Full code of the app to test loading a prophet model in azure function app in VS Code:

import pickle
from fbprophet import Prophet

# load the model from disk
filename = "c:/prophet_quickstart_model.sav"

with open(filename, "rb") as input_file:
    m=pickle.load(input_file)


future = m.make_future_dataframe(periods=100)
future.tail()

forecast = m.predict(future)
forecast[['ds', 'yhat', 'yhat_lower', 'yhat_upper']].tail()

A screen shot below shows the selected virtual envionment in VS Code which case prophet package:

Any help is appreciated.

yes i run from the terminal window in VSCode

This would lead us to a simple conclusion that this issue isn’t related to the Python extension. As the terminal is something that is part of the core VS Code editor. I’d suggest you raise this issue in the Azure CLI tools repo.
