错误：Python3 中 Jupyter 笔记本上的“导入 Pandas”失败

Question

I am having an issue trying to import pandas on my Jupyter notebook using Python 3.10. I am using a MacOS computer with VSCode as my IDE.

I have installed pandas on my machine using Homebrew brew install pandas and it works just fine when I use import pandas in my IDE. However, it fails in Jupyter.

I open jupyter as normal with jupyter notebook . I then attempt the simple command import pandas I get an error message that says:

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
Input In [1], in <cell line: 1>()
----> 1 import pandas

ModuleNotFoundError: No module named 'pandas'

I did a quick search on Stack and across Google and everybody tells me to run !pip install pandas in the Jupyter notebook but since I am using PHP3.10, I have opted for !pip3 install pandas . When I do this, Jupyter tells me:

Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: pandas in /Users/daveshields/Library/Python/3.10/lib/python/site-packages (1.4.2)
Requirement already satisfied: python-dateutil>=2.8.1 in /Users/daveshields/Library/Python/3.10/lib/python/site-packages (from pandas) (2.8.2)
Requirement already satisfied: numpy>=1.21.0 in /Users/daveshields/Library/Python/3.10/lib/python/site-packages (from pandas) (1.22.4)
Requirement already satisfied: pytz>=2020.1 in /Users/daveshields/Library/Python/3.10/lib/python/site-packages (from pandas) (2022.1)
Requirement already satisfied: six>=1.5 in /Users/daveshields/Library/Python/3.10/lib/python/site-packages (from python-dateutil>=2.8.1->pandas) (1.16.0)

I close Jupyter and then open it again and attempt import pandas and I get the exact same message. Can anyone help me figure out why this is happening? I am doing the Python Master Course by Ardit Sulce on Udemy but I can't progress any further in the course until I can figure this out. TYIA.

Answer 1

You can use:

import sys   
!{sys.executable} -m pip install pandas

If you already have Pandas in your system and still not able to load it then :

import sys  
sys.path.append('your-path')

Thank you so much to Wayne!

Amazingly the %pip install pandas worked! I did that and it installed pandas and numpy.

I ran import pandas and then df1 = pandas.DataFrame([[2,4,6],[10,30,30]]) .

After that I was able to successfully use print(df1) and it worked!
