pandas not found when it's supposed to be installed

[datomnurdin]

I got this error message. Already installed pandas.

>>> import pandas as pd
Traceback (most recent call last):
  File "analyze_tweets.py", line 9, in <module>
    import pandas as pd 
ImportError: No module named pandas

SOLUTION (by @datapythonista)

This error happens when Python can't find pandas in the list of available libraries. Python has internally a list of directories where it'll look for packages. These directories can be obtained with import sys; sys.path.

In one machine you can (and should) have several Python installations. Meaning that you can have pandas installed in one, and be using another Python installation (this is likely the case here).

In Linux/Mac you can run which python and will tell you which is the Python you're using. If it's something like /usr/bin/python, you're using the Python from the system, which is not a great practice, and rarely used in the Python community.

If you used Python before you may have used virtual environments and pip. While this is fine for many Python projects (e.g. Django), when using data projects (pandas, numpy, tensorflow...) this is discouraged. It's easy that you have installation errors, and also the libraries can run much slower when using pip.

The widely used solution to this problem is to use conda. You can find simple installation instructions for pandas in this document: https://dev.pandas.io/getting_started.html

For more advanced users, installing miniconda, and then manually install pandas (and any other required package) with conda can be preferred (but avoid this if you're starting, since you'll probably have errors of missing dependencies when using many of the pandas features).

you don't have pandas installed

see instructions here

you are also not showing what you did, nor your platform, so impossible to advise anything

[datomnurdin]

I already installed Pandas and I'm using Centos 7.

[jreback]

if you can't import it then its not installed. and you shouldn't be pathing at all. this indicates a problem with how you installed things.

[datomnurdin]

edit from @TomAugspurger: Don't use sudo pip install.

You can check my output message here after I run sudo pip install pandas.

sudo pip install pandas
Requirement already satisfied (use --upgrade to upgrade): pandas in /usr/lib64/python2.7/site-packages

[jreback]

same answer. you probably have multiple pythons installed. pls read the installation instructions and follow them.

I'm facing a similar issue.

Could you have a look here ?

I also had the same issue and had both python3, python versions installed.

sudo pip3 install pandas

try that it worked for me.

[gfyoung]

sudo pip3 install pandas

The original issue is for Python 2.x, so unfortunately, this suggestion is moot. On Linux, do the following:

which python
which pip

and see where each is pointing to. Something tells me you'll find a discrepancy. If not, chase down where your "existing" pandas installation is located and see whether it is actually installed there.

I am facing the following issue in my code:

`ImportError Traceback (most recent call last)
in ()
----> 1 import pandas as pd
2
3 import numpy as np
4
5 import matplotlib.pyplot as plt

ImportError: No module named pandas`

Even though I have installed pandas.

I am using Jupyter notebook.

[RANAJITGIT]

I am facing the same issue.
I have python 3.6 and panda installed
import pandas as pd is working fine in jupyter notebook.
but I am getting error in python shell.
Please help...............

[gfyoung]

Do you have multiple python versions installed? Try this in the Python shell:

import sys
print(sys.version_info)

[ram1421]

is the issue with fixed. How ?

Traceback (most recent call last):
  File "e:\Learn\TensorFlow\script.py", line 5, in <module>
    import pandas as pd
ModuleNotFoundError: No module named 'pandas'

[dduque10]

It is better to use a virtual environment to avoid these trouble https://stackoverflow.com/questions/49265260/pandas-unrecognized-by-python3/49265845#49265845

[RANAJITGIT]

I used pip install pandas in cmd and it works. The issue was not because of multiple Python versions. Because jupyter has panda configured so its working in jypyter. How ever to run it on IDLE we need to panda in cmd. Regards, Ranajit

I ran into this issue in my virtual environment.

pip install pandas in my virtualenv ran fine. No errors. Dropping into my python shell though I could not import it and pip freeze did not report it as installed.

To get around it I had to delete and recreate my python virtual environment, re-installed my pip requirements from my requirements.txt, pip install pandas and all was good.

Still a mystery to me....

[thomasschijf]

edit from @TomAugspurger: don't use sudo pip install

for python 2:

sudo pip2 install pandas

[TomAugspurger]

caskroom/cask/panda looks like a different piece of software.

@thomasschijf in general, you'll want to avoid sudo pip. That has a tendency to mess up your system's python install.

[AmnaKhan1]

My problem resolved by using pip3 install pandas. Python version was 3.5.*.

[Sonupival6]

I am looking for simulation of KNN algorithm for temperature in python or in MATLAB . IF any one can provide me the code than that will be great.
cheers.

You probably have some .py files in your working directory with the same name as one of the modules you're trying to use. The names of modules should not be used as file names in your project.

[siposm]

pip2 install pandas worked for me. i'm planning to clear out everything and get rid of the plenty of different versions and use only one (or virtual environments as a lot of ppl suggested:))

[RobStelling]

If you installed pandas (with pip/conda) and it doesn't show up in python then probably the python in your path is not the same that pip/conda are updating.
Double check your conda directory (Usually: /home//anaconda3/bin/) and run the python instance on this folder. If pandas is installed there (and I bet it will be) then add this folder to the beginning of your path.

[Wessi]

I fixed the same problem with the below commands...
Type python on your terminal. If you see python version 2.x then run these two commands to install pandas: sudo python -m pip install wheel and sudo python -m pip install pandas. Else if you see python version 3.x then run these two commands to install pandas: sudo python3 -m pip install wheel and sudo python3 -m pip install pandas. Good Luck!

[Wessi]

I am facing the same issue.
I have python 3.6 and panda installed
import pandas as pd is working fine in jupyter notebook.
but I am getting error in python shell.

Just wanted to add to the answer provided by @pavankat

What he suggested worked for me, but I had to download Python 3.7 first!
