I am trying to create a Data Science project using some Quandl dataset, but am receiving an error on import.
As i know quandl should be imported all in lowercase, as the documentation states here and here, my import goes as follows:
import quandl
Error:
ModuleNotFoundError: No module named 'quandl'
I installed quandl using pip install quandl. My pip list output is:
Package Version

requests 2.22.0
setuptools 41.0.1
six 1.12.0
urllib3 1.25.3
wheel 0.33.4
wincertstore 0.2
I don't have pip3, as I installed Python through my Anaconda installation. I am running a Jupyter Notebook in a virtual environment I created just for this project. Just so you know, python --version output is:
Python 3.7.3
The strange part occurs when i try running a one line python script with import quandl. This time the program runs without errors, which means that the cause of the ModuleNotFoundError: No module named 'quandl' is the jupyter notebook, which is not being able to properly find the quandl module.
As a last resource, I tried installing quandl inside jupyter notebook:
!pip install quandl
import quandl

The problem was that Jupyter was not properly recognizing my virtual environment. I found my answer here, the workaround is pretty self explanatory.
