I'm on MacOSX Mojave 10.14.6 on a MacBook Pro 2015. So I pip installed sympy, right?
I head over to my shell, run python3, and do:
$python3

>>> import sympy
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'sympy'
Just to be sure, I pip installed again just to make sure.
$ pip install sympy
Requirement already satisfied: sympy in /usr/local/lib/python3.7/site-packages (1.4)
Requirement already satisfied: mpmath>=0.19 in /usr/local/lib/python3.7/site-packages (from sympy) (1.1.0)
My pip list also includes sympy as sympy 1.4.
What's wrong here? Is there another setup step I've missed?
Apparently all I had to do was
python3 -m pip install sympy
Mac being weird with two built in pythons and a third python for user.
Pro tip: use a virualenv.

I am trying to download and use SciPy. According to pip I have already downloaded it however when I try to use it python says there is no module named SciPy. I have tried using python as well as python3. Here is a copy of my console:

I used pip3 to install tensorflow.. And after installation, I can find it in
/usr/local/lib/python3.6/site-packages
Besides， I use pip3 list and find it on the list:
vincent#ubuntu:/usr/local/lib/python3.6/site-packages/tensorflow$ pip3 list

What's wrong with it?
I ran it in Linux14.04(x64) in VMware
There may be multiple versions of python installed. You can do the following to ensure that tensorflow is installed for the version you are using -
python -mpip install tensorflow
Here I assume that you are using python prompt to run python. If you are using a different prompt just use that in place of python.
I'm trying to run a script of mine using Python 2.7. When I run
python2.7
I get

When I try to run my script, I get:

import numpy as np
ImportError: No module named numpy
So Python 2.7 doesn't seem to know about numpy. When I run
pip2.7 install numpy
I get:
Requirement already satisfied (use --upgrade to upgrade): numpy in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python
Cleaning up...
Any idea what's going on here?
Thanks!
This might be because you're using the wrong python distro on your computer. If you are using an OSX machine, there might be a python distribution in /usr/local/ and one in /System/Library/Frameworks. It seems like python2.7 might be linked to the one in /usr/.
Try
which python2.7
should locate which python distro "python2.7" is symlinked to. If you're symlinked to /usr/, just change it to the one in /System/Library and your numpy should work.
I am coming across a strange problem, I already installed python packages but it doesn't recognize them. please note that some packages are recognizable.

>>> import requests
Traceback (most recent call last):

ImportError: No module named requests
Whenever I try to install it using Pip like
sudo pip install requests
I got this message whenever I try to install the same package.
Requirement already satisfied (use --upgrade to upgrade): requests in /usr/local/lib/python2.7/site-packages
What should I do to solve this problem ?
UPDATE_1
pip --version
pip 7.1.2 from /usr/local/lib/python2.7/site-packages
Find where pip installs your package and add the path to
export PYTHONPATH=<path>
#my path was /Library/Python/2.7/site-packages
in your .bashrc or .profile file.

Has anyone had this problem?
I uninstalled it using
pip uninstall mandrill
and reinstalled it using the python -m option:
sudo python -m pip install mandrill
Now it works perfectly.
