I am not a python lib installing pro...so obviously i made something wrong. But how do i fix that?
Maybe i have to say i am working on a M1 Macbook
looks like you may need to repoint your pycharm to your installed python interpreter.
go to command line and find out python interpreter path. On windows you can where python in your command line an it will give you where your python and packages are installed.. You could also activate python directly in command line and find paths from there. For example, open command line then;
python
press enter = activates python
within then you can do:
import sys
for x in sys.path: x
In pycharm make sure you point to path discovered from step 1 and select that to be your python interpreter within pycharm --- check out examples here https://www.jetbrains.com/help/pycharm/configuring-python-interpreter.html#add-existing-interpreter
Should work. Not sure about all the steps you took, but if you installed python with pycharm on top of your regular installation of python i would recommend :
finding all the paths from step 1
deleting python using system
checking if folders found from paths step still exist
if they do, delete those as well
start over just with one python installation
repoint to that in pycharm
first
pip uninstall PIL
after uninstall
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
or
brew install Pillow

I have Pillow installed successfully on my Mac, but when I type in
from PIL import Image
I get an error: "Unable to import 'PIL'
I'm using VSCode by the way. Anyone know how to fix this? I've looked through almost every stack overflow post, but can't seem to figure it out. I tried uninstalling and reinstalling, deleting PIL, etc. I have Pillow-7.1.2 by the way.
If you installed Pillow with:
pip install pillow
then you can find where it is installed with:
pip show pillow
Sample Output
Name: Pillow
Version: 7.1.2
Summary: Python Imaging Library (Fork)
Home-page: https://python-pillow.org
Author: Alex Clark (PIL Fork Author)
Author-email: aclark#python-pillow.org

Location: /usr/local/lib/python3.7/site-packages <--- HERE
Of course, if you installed with:
pip3 install pillow
you will need:
pip3 show pillow
Now go to your Python interpreter and check where it is looking for packages and you will surely work out the problem:
python3 -c "import sys; print(sys.path)" | tr , '\n'
Samnple output
[
'/usr/local/Cellar/python3/3.6.3/Frameworks/Python.framework/Versions/3.6/lib/python36.zip'
'/usr/local/Cellar/python3/3.6.3/Frameworks/Python.framework/Versions/3.6/lib/python3.6'
'/usr/local/Cellar/python3/3.6.3/Frameworks/Python.framework/Versions/3.6/lib/python3.6/lib-dynload'
'/usr/local/lib/python3.6/site-packages'
'/usr/local/Cellar/numpy/1.13.3/libexec/nose/lib/python3.6/site-packages']
Of course, if you start Python with python rather than python3, you will need:
python -c "import sys; print(sys.path)" | tr , '\n'
Finally, go to your Terminal and find out what your shell actually runs when you enter python by running:
type python # or "type python3" if you normally enter "python3"
Now go in your IDE and see which Python that runs:
import sys
print(sys.executable)
The version of my Python is 2.7.13.
I run the following in Jupyter Notebook.
Firstly, I installed the packages
%%bash
pip uninstall -y google-cloud-dataflow
pip install --upgrade --force tensorflow_transform==0.15.0 apache-beam[gcp]
Then,
%%bash
pip freeze | grep -e 'flow\|beam'
I can see that the package tensorflow-transform is installed.
apache-beam==2.19.0
tensorflow==2.1.0
tensorflow-datasets==1.2.0
tensorflow-estimator==2.1.0
tensorflow-hub==0.6.0
tensorflow-io==0.8.1
tensorflow-metadata==0.15.2
tensorflow-probability==0.8.0
tensorflow-serving-api==2.1.0
tensorflow-transform==0.15.0
However when I tried to import it, there are warning and error.
WARNING:tensorflow:From /usr/local/lib/python2.7/dist-packages/tensorflow_estimator/python/estimator/api/_v1/estimator/__init__.py:12: The name tf.estimator.inputs is deprecated. Please use tf.compat.v1.estimator.inputs instead.

1 import tensorflow as tf
----> 2 import tensorflow_transform as tft
3 import shutil
4 print(tf.__version__)
ImportError: No module named tensorflow_transform
After some investigation, I think I have some ideas of the problem.
I run this:
%%bash
pip show tensorflow_transform| grep Location
This is the output
Location: /home/jupyter/.local/lib/python3.5/site-packages
I tried to modify the $PATH by adding /home/jupyter/.local/lib/python3.5/site-packages to the beginning of $PATH. However, I still failed to import tensorflow_transform.
Based on the above and the following information, I think, when I ran the import command, it executes Python 2.7, not Python 3.5
import sys
print('\n'.join(sys.path))
/usr/lib/python2.7
/usr/lib/python2.7/plat-x86_64-linux-gnu
/usr/lib/python2.7/lib-tk
/usr/lib/python2.7/lib-old

/usr/local/lib/python2.7/dist-packages
/usr/lib/python2.7/dist-packages
/usr/local/lib/python2.7/dist-packages/IPython/extensions
/home/jupyter/.ipython
Also,
import sys
sys.executable
'/usr/bin/python2'
I think the problem is tensorflow_transform package was installed in /home/jupyter/.local/lib/python3.5/site-packages. But when I run "Import", it goes to /usr/local/lib/python2.7/dist-packages to search for the package, rather than /home/jupyter/.local/lib/python3.5/site-packages, so even updating $PATH does not help. Am I right?
I tried to upgrade my python, but
%%bash
pip install upgrade python
Defaulting to user installation because normal site-packages is not writeable
Then, I added --user. It seems that the python is not really upgraded.
%%bash
pip install --user upgrade python
%%bash
python -V
Python 2.7.13
Any solution?
It seems to me that your jupyter notebook is not using the right python environment.
Perhaps, you installed the package under version 3.5,
but the Notebook uses the other one, thus it cannot find the library
You can pick the other interpreter by clicking on: Python(your version) - bottom left.
VS-Code - Select Python Environment 1
However you can do this also via:
CNTRL+SHIFT+P > Select Python Interpreter to start Jupyter Server
If that does not work make sure that the package you are trying to import is installed under the correct python environment.
If not open up a terminal, activate the environment and install it using:
pip install packagename
For example i did the same thing here: (Note: I'm using Anaconda)
installing tensorflow_transform
After a installation, you can import it in your code directly like this:
importing tensorflow_transform
I have tried pip install psycopg2 and following errors i got:

Now I am not able to understand what to do. Thanks
Edit 1:
I have also added my PostgreSQL path to system path variables
path:C:\Program Files\PostgreSQL\9.4
path:C:\Program Files\PostgreSQL\9.4\bin
The correct answer was given by Craig Ringer, I am just adding this because I came to know that we should first check which version of 64 bit or 32bit Python installed on our system. If you have 32 bit version of Python and if you will try to install 64bit, then you will get the above error on importing.
For checking the version:
import platform
platform.architecture()
and you will get an output like this:
('32bit','WindowsPE')
Download the pre-packaged binary release of psycopg2 for Windows rather than compiling it yourself. It's a pain to compile on Windows. This is explained in the install documentation for psycopg2.
You might need to remove your half-installed attempts.
Choose the appropriate version from this page:
http://www.stickpeople.com/projects/python/win-psycopg/
Right click and select copy link address
Back at home, use easy_install <<Paste URL Here>>
Freeze your new requirements: pip freeze > requirements.txt
Now that psycopg is in PyPI (as of March 2017 it appears), just fire up a command prompt with administrator privileges and install like so:
python -m pip install -U pip
python -m pip install psycopg2
If you don't have pip installed, follow the instructions here to do that first:
https://stackoverflow.com/a/12476379/2540707
pip install psycopg2-binary
This worked for me
Step 1: Compilers Installation and configuration
https://wiki.python.org/moin/WindowsCompilers
Before do anything, install or upgrade the Setuptools Python package. It contain compatibility improvements and add automatic use of compilers:
pip install --upgrade setuptools
Step 2: Download and install PostgreSQL
Before you continue to install python packages inside you virtualenvs download postgres itself. It contains files that are needed when compiling the psycopg2 python package. Just use the PostgreSQL installer(version 10 for example).
Important: add the postgres C:\Program Files\PostgreSQL\10\bin folder to your path. It contains the .dll needed for psycopg2.
Step 3: Install psycopg2
pip install psycopg2
Tested on Windows 7 + python 3.7
The best/easiest way of installing packages (including this problematic psycopg2 ) for python on windows platform is to:
1) install anaconda and ...
2) use Anaconda Navigator GUI to install/update packages.
By this one avoids many inconsistencies and conflicts that occurs among different packages versions and installations.
How do I install PIL?
>pip install PIL
Downloading/unpacking PIL
Could not find any downloads that satisfy the requirement PIL
Some externally hosted files were ignored (use --allow-external PIL to allow).
Cleaning up...
No distributions at all found for PIL
Storing debug log for failure in /root/.pip/pip.log
>pip uninstall PIL
Can't uninstall 'PIL'. No files were found to uninstall.
pip install PIL --allow-external PIL --allow-unverified PIL
This is due to changes in the new version of Pip. Run pip --version and I'm willing to bet you are running 1.5. See the changelog here. This new default behavior enhances security. In PIL's case, the file you are installing actually comes from effbot.org (thus --allow-external) and PyPi doesn't have a checksum to guarantee validity (thus --allow-unverified).
Also, you might consider using the Pillow replacement to PIL.
Updated info for those reading in 2016:
--allow-external
and
--allow-unverified
were recently deprecated. Installing packages external to PyPi using pip is no longer supported: http://www.python.org/dev/peps/pep-0470/
As an alternative, when you really need to install that external package, you can download the source code and run its setup.py. For example, for PIL 1.1.7, download from http://www.pythonware.com/products/pil/, then:
$ tar xvfz Imaging-1.1.7.tar.gz
$ cd Imaging-1.1.7
$ python setup.py install
(^ from the PIL README)
If you only want to install the package to a specific virtualenv, you can just activate your virtualenv first. ** thanks #Caumons
Alternatively, substitute the path to your virtualenv for 'python' in the third line, e.g.:
$ /home/username/virtualenv-name/bin/python setup.py install
I recently lost my HDD and am currently in the process of rebuilding my laptop (running Mountain Lion) dev system. This afternoon I went to install virtualenvwrapper and ran into some weirdness that prevents me from installing virtualenvwrapper.
I've done the following:
Installed setup tools.
Used easy_install-2.7 to install pip.
Used pip-2.7 to install virtual env.
When I go to install virtualenvwrapper using pip-2.7, I get the following (see below). The -2.5,-2.6,-2.7 suffixes seem to be a new thing for mountain lion? I've tried the same process without the suffixes, but that didn't work either.
I'm posting because I suspect something is majorly awry here, and would like to get to the bottom of it before it becomes a more insidious problem down the road.
Is it better for me to download and install a fresh version of 2.7, and set up my paths to use it?

What p4tux said
virtualenv is now using distribute not setuptools
export VIRTUALENV_DISTRIBUTE=true
before you create the environment with
virtualenv ENV
or do
$ python virtualenv.py --distribute ENV
See virtualenv documentation
virtualenv is now using distribute not setuptools
export VIRTUALENV_DISTRIBUTE=true

https://gist.github.com/3179227
(using pythonbrew) seems to have sorted the issue out for me temporarily. I'd like to not have another component in the mix (pythonbrew), so hopefully someone else will weight in with how to get virtualenv to play nicely with ML.
