How do I fix the error "The specified module could not be found" when loading import statsmodels?

Statsmodels is installed in my computer and I am trying to run some files from the terminal through python3
When I try to run a .py file with import statsmodels.api as sm I get an error
Any ideas on what the issue is?

did you do pip install statsmodels
or pip3 install statsmodels
it may have installed it to the wrong python version if you did not specify pip3

Why my terminal is not allowing to use pip?? But allowing pip3

I was trying to install pandas and using "pip install pandas"
But my Terminal was not allowing me to use pip.
When I tried pip3 instead of pip, pandas download was completed.
Although, my problem was not solved as I am still not able to import pandas in my SUBLIMEText3.
Anyone can help?

When you are trying to install pandas or other packages in python2 write this in your terminal:
python -m pip install pandas
And for python3 write this in your terminal:
python3 -m pip install pandas

Thanks for showing some points which helped me to find the answer.
pip install pandas was not allowed so I used pip3 install pandas to download.
I later checked in sublime Text3 which version of Python it is running using below:
import sys
print(sys.version)
The result shows: 2.7.16
So, I have changed the version to Python 3 using these steps: Tools-->Build System-->Python3
Now, I can see Pandas running
Although, I was not sure why terminal was not finding pip.

Installing matplotlib on windows 10 python 3.6

HI I am following an install from a book "Python Crash Course" chapter 15 which directed me to install matplotlib via downloading from pypi and using the format
python -m pip install --user matplotlib-2.2.2-cp36-cp36m-win32.whl
This seems to go ok but reports at the end.
File "C:\Program Files (x86)\Python Community\Python 3.6.1\lib\decimal.py", line 3 in , from decimal import *
AttributeError: module 'numbers' has no attribute 'Number'
and when I enter an interactive shell:
import matplotlib
I get a ModuleNotFoundError
I have tried a matplotlib-2.2.2-cp36-cp36m-win32.whl and matplotlib-2.2.2-cp36-cp36m-win_amd64.whl both give the same error.
Could someone please let me know how to fix this?

I am answering my own question.
The issue was to do with a file called numbers.py residing in a folder that I have all my python files, wheel files etc.
I found the answer in stack overflow. I will link to this matplotlib - AttributeError: module 'numbers' has no attribute 'Integral'.
The file was stopping the install so I renamed it and reinstalled matplotlib and it now works.
Sorry but this was not obvious to me !

Try running cmd as administrator inside the python directory. Then execute:
pip3 install matplotlib-2.2.2-cp36-cp36m-win32.whl
Also make sure that you have all dependencies installed.

The code seems very specific and something may not be supported any more.
You could first uninstall the current version using:
pip uninstall matplotlib
and then try installing matplotlib as follows:
pip install matplotlib
providing that you have admin rights to do so.
Then you can import as: import matplotlib.pyplot as plt

It seems like you are installing the package on Python 2.
Try installing the library using:
py -3 -m pip install --user matplotlib
Assuming you are using Windows.

Try doing as below:
python -m pip install --user matplotlib

No Module named "sklearn"

I am trying to import 'sklearn' using Python 3.4.3 on a Raspberry Pi 3 running Raspian.
I downloaded microconda3, which includes all the necessary modules to use scikit.
However, when I attempt to import 'sklearn' in IDLE, I receive an error stating that there is no module named 'sklearn'.

Try starting fresh and reinstall all of the necessary modules through miniconda3. Maybe the scikit-learn included on that install did not work.
You can then try
sudo apt-get install python3-scipy python3-sklearn

You can install the module with the following command using pip:
pip install -U scikit-learn.
See: Scikit-learn Docs

Can't import sklearn and scipy. Windows 7

I'm trying to set all of this up on Windows 7. This is the error I get when I try to import sklearn or scipy. I've installed sklearn and scipy using whl files. I don't remember what I used to install numpy but I can import numpy without trouble.

In my case I couldn't install scipy using pip install scipy, I finally managed to get it installed by using Scipy from here, and installing it as follows:
pip3 install scipy-0.19.0rc2-cp36-cp36m-win_amd64.whl
When I finally had scipy installed, my numpy stopped working and started giving that error. So I decided to install numpy from here:
pip3 install numpy-1.12.0+mkl-cp36-cp36m-win_amd64.whl
Make sure that you install the correct numpy for your architecture and version of Python.
I hope that helps you, cheers.
