[SOLVED] Why does it keep saying ImportError: No module named pydot when I have already installed the module through pip?

Why does it keep saying ImportError: No module named pydot when I have already installed the module through pip?

I used command pip install pydotto install module pydot but whenever I try to run a certain file through terminal it says the following error.

Traceback (most recent call last):
  File "src/parser.py", line 3, in <module>
    import pydot
ImportError: No module named pydot

I have done endless checking to make sure it was properly installed. I did check it in the python folder and it is there, indeed.

Does anyone know what am I missing? Is there something wrong with how it was installed?

I am using a macOS.

Thank you very much!

Solution

First, check where the module is installed (type the following in the console):

pip show numpy

This returns the following for me (Macbook):

Name: numpy
Version: 1.14.0
Summary: NumPy: array processing for numbers, strings, records, and objects.
Home-page: http://www.numpy.org
Author: NumPy Developers

Requires:
Required-by: tensorly, tensorflow, tensorflow-tensorboard, scipy, patsy, pandas, nitime, nipype, mxnet, matplotlib, Keras, h5py

You can see the location field:

Location: /Users/lab/miniconda2/lib/python2.7/site-packages

This means that to make it run properly, I need to use:

python2 myscript.py

If you want to use python 3. then use

pip3 install pydot

and then

python3 myscript.py
