I followed Microsoft's tutorial https://code.visualstudio.com/docs/python/data-science-tutorial and installed miniconda, I use it's python interpretor, and tried to import the following :
import math
import pandas_datareader as web
import numpy as np
import pandas as pd
from sklearn.preprocessing import MinMaxScaler
However pandas_datareader won't be recognized, but is already installed as it says "requirements already satisfied" when I try to add it from either conda or pip. I don't get why my virtual environnement won't find it after browsing the web for hours, with no luck.
By default all the installations you do will be in base environment and not in the virtual environment.
You'll have to activate the virtual environment in conda and then do a pip list to check if the package is present:
conda activate your_env_name
pip list
If it's not present, then install it here and try it out. Should work fine.
