no module named Pillow

On Windows 10 pro, I am running a docker image with python and jupyter installed. I can start the docker image and from that shell start the jupyter notebook fine. Both python2 and python3 kernels are available. PIL and Pillow are installed but I cannot import them. See below:
(I have indicated the contents of each jupyter cell with double asterisks.
The result of each cell then simply follows below it)
**!pip install Image**

You are using pip version 19.0.3, however version 19.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
**!pip install Pillow**
Requirement already satisfied: Pillow in /usr/lib/python3/dist-packages (5.1.0)
You are using pip version 19.0.3, however version 19.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
**!python -m pip install pillow**
Requirement already satisfied: pillow in /usr/lib/python3/dist-packages (5.1.0)
You are using pip version 19.0.3, however version 19.1 is available.

**import PIL**

ImportError: No module named pillow
But when I exit the notebook and start an interactive python session in the running docker container, PIL is found easily:
root#7092fc2336d3:/# python
Python 3.6.7 (default, Oct 22 2018, 11:32:17)
[GCC 8.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import PIL
>>>

well this is weird. It turns out that the pip in jupyter was installing in the python3 site packages but the python in the jupyter notebook was looking in the python2 site packages. so when I installed pillow in a jupyter cell like so
!/usr/bin/python2.7 -m pip install Pillow
now this works
import PIL.Image

Numpy requirement not satisified for Pandas

I am working on jupyter-notebook.
When i give the command
import pandas
df = pandas.read_csv('/home/pglab1/WiFi Strength_Mar06.csv')
print(df)
it shows the following error:
ImportError Traceback (most recent call last)

ImportError: this version of pandas is incompatible with numpy < 1.12.0
your numpy version is 1.11.0.
Please upgrade numpy to >= 1.12.0 to use this pandas version
in the same notebook, when I give the command,
!pip install pandas,
the output is

cheetah 2.4.4 requires Markdown>=2.0.1, which is not installed.
You are using pip version 10.0.0, however version 19.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
I am not familiar with software environment, so kindly help me how to correct this.( The problem is Pandas require a numpy package >1.12.0 but the numpy package in .../dist-packages is 1.16.2. this is my understanding)

This works in such situations
import sys
!{sys.executable} -m pip install numpy

Try:
pip install --upgrade pip
pip install markdown
pip install --upgrade numpy
pip install pandas

You might want to install using the following command:
import sys
!{sys.executable} -m pip install pandas
rather than just !pip install pandas - this will ensure that you are using the right pip for associated with the kernel.

import pandas as pd ImportError: No module named pandas

I can't seem to import panda package. I use Visual Studio code to code. I use a mac and have osX 10.14 Majove.
The code that i am trying to compile is :

You need to install pandas with:
pip install pandas
If you run into issues with privileges, you may need to run:
sudo pip install pandas
It is also possible on Python 3 that you may need to run:
pip3 install pandas (although pip may be pointing to pip3 already). You can read about differences between pip versions on this SO post.
If you don't have pip installed, see here for installation.

Check pandas package path from your env with:
jupyter kernelspec list
If you see the path:
/Users/yourname/Library/Jupyter/kernels/yourenv
Delete that Jupyter folder from Library and run again.

if you see such this in your IDE and the error "no module named pandas" when you run your code, it means that pandas has not been installed although you have done "pip install pandas" or whatever.
Go to file > settings > project interpreter and see if pandas is available in the list of packages. if not simply click + (plus), choose pandas and install it in your project environment .
see picture
then wait for you IDE update your project skeletons ... voila , the error disappears !

When entering the command to run your file, make sure you specify which version of python you're using. For example, instead of python filename.py, use python3 filename.py or python2 filename.py

your pandas is installed in python3 (3.7):
Requirement already satisfied: pandas in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (0.24.0)
but you are running python2.7 and pandas isn't in your path 2.7:
['/Users/thibaultmonsel/Desktop/ML_folder',
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip',
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7',
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin',
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac',
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages',

'/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python',
'/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC']
try to simply run your script using python3:
python3 help1.py
or add python3 header, example:
#!/usr/bin/env python3
or
#!/usr/local/bin/python3
and if that doesn't work (like I had the same problem because I was importing pandas from jupyter notebook, macos), you can ultimately import from your --user path, example:
sys.path.append("/Users/<USER>/Library/Python/3.7/lib/python/site-packages")
but make sure you have pandas installed there (..python/site-packages/pandas) using
pip3 install pandas --user

Check your virtual environment (you can see it at the left corner of VS code) and install the package (e.g. pandas) in your virtual environment like this:
conda install -n yourenvname [package]

install pandas outside the project, I wanted to download it only for an env environment but I got the same error so I did it from outside.

Code > Preferences > Settings
In Search, type "interpreter"
You will see a bar : Python: Default Interpreter Path
Paste your correct path to Python (something like "/usr/local/bin/python3" in Mac), it will automatically save
Then go back to your python file and try to run

For me, the below command works in MAC
sudo -H pip3 install pandas --upgrade

ImportError: No module named attr

I have only very rudimentary experience in Python. I am trying to install the package pyslim (see here on the pypi website). I did

I am using Python 2.7.10 on a MAC OSX 10.11.6. Not sure if it matter but I usually install things with homebrew. I am using pip 18.1 from /usr/local/lib/python2.7/site-packages/pip (python 2.7).
Edit
$ which python
/usr/bin/python
$ which pip
/usr/local/bin/pip

Take a look to this other question that is related to the attrs package.
In your case, you have attr and attrs installed at the same time, and they are incompatible between them, so python is unable to resolve the package name on the import correctly.
You should use attrs only, so try uninstalling attr and try it again:
python -m pip uninstall attr
If, in the future, you need to have some packages incompatibles between them, take a look about using virtual environments in Python, which are really easy to use and will be very useful to play with packages and packages versions without break anything.

First uninstall pyslim. Use "pip uninstall pyslim". Then try installing again using
"conda install -c conda-forge pyslim"
Refer https://anaconda.org/conda-forge/pyslim

On the other side, if I run python3, it works for import boto3 but not import boto.

Install like this:
python -m pip install --user boto3

I ran into this same issue the other day. I had python 2.7 installed on my Mac (there by default I presume). I then installed homebrew and used it to get the latest version of python setup: brew install python
Then, I had two versions of python, which is okay. Brew installed pip3 along with Python 3.6.5.
So then, I was able to run this to get boto3: pip3 install boto3
To ensure that it is accessible, use the python3 command, not the older python. So in my case, I ran my code with:
python3 signURL.py

Just in case this worked for me after upgrading to ansible 2.4.0.0:
pip install --upgrade --user boto3
That recreated my $HOME/Library/Python/2.7/lib/python/site-packages

so I'm an uber noob at python, doing something for work but posting just in case this helps someone... I had the same error and all it was was that I had everything downloaded under python3 and I was typing the python some_script.py causing the:
File "some_script.py", line 4, in <module>
import boto3
changing it to python3 some_script.py fixed it/found the proper module
