ImportError: No module named statsmodels

I downloaded the StatsModels source from this location.

Then untarred to

/usr/local/lib/python2.7/dist-packages 

and per this documentation, did this

sudo python setup.py install 

It installed but when I try to import

import statsmodels.api as sm 

I get the following error

Traceback (most recent call last): File "/home/Astrophysics/Histogram_Fast.py", line 6, in <module> import statsmodels.api as sm ImportError: No module named statsmodels.api 

I read a few post with a similar problem and checked that setuptools was installed and it was also in

/usr/local/lib/python2.7/dist-packages 

I'm kinda of lost on this and would appreciate any help...

I am also running

numpy 1.6 

so thats not the problem.

• you shouldn't untar it to /usr/local/lib/python2.7/dist-packages (you could use any temporary directory)
• you might have used by mistake a different python executable e.g., /usr/bin/python instead of the one corresponding to /usr/local/lib/python2.7

You should use pip corresponding to a desired python version (use python -V to check the version) to install it:

$ python -m pip install statsmodels 

It would allow you to upgrade/uninstall it easily.

Don't install as a root to avoid the risk of messing with system python installation by accident. You could use --user option or virtualenv instead.

As per documentation, you can install using the following commands

pip install --upgrade --no-deps statsmodels 

using conda

conda install statsmodels 

Then restart your jupyter notebook

if you facing an error like no module pasty stop your jupyter notebook and try the below command on terminal

pip install patsy 

Don't forget to restart your jupyter notebook Let's hope

Install patsy:

pip install --upgrade patsy 

Install statsmodels

pip install statsmodels 

docs here

You have to upgrade the package pytest. I had the same issue importing in a Jupyter notebook on Ubuntu python 2.7

import statsmodels.api as sm

I also had to restart the Jupyter notebook.

sudo python -m pip install pytest --upgrade

Try installing using the path directly,

For example, pip install --user "downloaded_package_path"

Then try importing the statsmodels, import statsmodels.api as sm

Until 2022 many things changed, but if somebody have the same problem, here is what worked for me: on the left side of VS Code, there are many icons (explore, search etc). The last one is Pip manager. Click on it and search for the module to install it :) Much better than 9 years ago haha

Install statsmodels:

For Window users:

pip install statsmodels

For Mac users:

pip3 install statsmodels
