I have installed pandas but cannot import in VScode

Question

My lap is MacBookPro2017, macOS Mojave 10.14.16

I used to coding in Jupyter and everything goes well.

However when I want to do the same thing in VScode, it said that

"ImportError: No module named pandas"

I am sure I have installed pandas by

pip3 install pandas

---

I do following things:

1.Search for similar problems on SO, and someone says there may be more than one version python, the pip and pandas may under another path. Then I find there are python2.7 and python3.7 in my lap:

AlfiedeMacBook-Pro:~ alfie$ which python3
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3
AlfiedeMacBook-Pro:~ alfie$ which python
/usr/bin/python
AlfiedeMacBook-Pro:~ alfie$ which pip
/Library/Frameworks/Python.framework/Versions/3.7/bin/pip
AlfiedeMacBook-Pro:~ alfie$ which pip3
/Library/Frameworks/Python.framework/Versions/3.7/bin/pip3
AlfiedeMacBook-Pro:~ alfie$ which pandas
AlfiedeMacBook-Pro:~ alfie$ pandas --version
-bash: pandas: command not found
AlfiedeMacBook-Pro:~ alfie$ pip --version
pip 19.2.2 from /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pip (python 3.7)

And if I type:

AlfiedeMacBook-Pro:~ alfie$ pip3 install pandas
Requirement already satisfied: pandas in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (0.25.1)
Requirement already satisfied: pytz>=2017.2 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from pandas) (2019.2)
Requirement already satisfied: python-dateutil>=2.6.1 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from pandas) (2.8.0)
Requirement already satisfied: numpy>=1.13.3 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from pandas) (1.17.0)
Requirement already satisfied: six>=1.5 in ./Library/Python/3.7/lib/python/site-packages (from python-dateutil>=2.6.1->pandas) (1.12.0)

So I think I have pandas in the true path(?)

2.Then I saw some one use sys to append the path, so I write it in front of my code:

import sys
sys.path.append('/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages')
import numpy as np
import pandas as pd

Then I got:

ImportError: this version of pandas is incompatible with numpy < 1.13.3

your numpy version is 1.8.0rc1.

Please upgrade numpy to >= 1.13.3 to use this pandas version

But my numpy version is 1.17, I have upgraded.

So I just want know what I should do to make the pandas can be used in VScode?

Answer 1

I had the same issue. The problem was that VS Code was using a different environment (shown in the lower left corner). Switching the environment there solved the issue.
