When installing python packages with poetry on Catalina OS I get this error for Pillow 6.2.1
The headers or library files could not be found for zlib,
a required dependency when compiling Pillow from source.
Even after I installed zlib with homebrew and added the relevant lines for the zshrc profile
export LDFLAGS="-L/usr/local/opt/zlib/lib"
export CPPFLAGS="-I/usr/local/opt/zlib/include"
I use python 3.8.0 which matches with the Pillow version I am trying to install.
I don't know what else to do.

I'm trying to use ONNX runtime for Ubuntu: https://onnxruntime.ai/
I selected Linux, C++, x64, then CUDA. It says "Install Nuget package Microsoft.ML.OnnxRuntime.Gpu
Refer to docs for requirements."
When I click on "Microsoft.ML.OnnxRuntime.Gpu", I'm taken to https://www.nuget.org/packages/Microsoft.ML.OnnxRuntime.Gpu
There, it just says "Install-Package Microsoft.ML.OnnxRuntime.Gpu -Version 1.8.1". Now what am I supposed to do?
They expect you to install nuget in linux with
sudo apt-get install -y nuget
And then run the following with the version you want installed.
nuget install Microsoft.ML.OnnxRuntime.Gpu -Version 1.12.0
That's the expected approach. Personally, for me that didn't work. I kept getting some error saying "'Microsoft.ML.OnnxRuntime.Managed' already has a dependency defined for 'System.Memory'." So I did it a different way. I just went to https://github.com/microsoft/onnxruntime/releases/tag/v1.12.0. And then at the bottom under assets it lists pre-built .tgz packages for the different setups. You can just download one and unpack it.
We had initially installed tesseract 3.04 in centos 7, and know switching to tesseract 3.05. We have un-installed the older versions and have already installed leptonica-1.75.3 downloaded from leptonica home site.
But, when we go for installing tesseract 3.05, we get following error
checking for LEPTONICA... no
configure: error: Leptonica 1.74 or higher is required. Try to install libleptonica-dev package.
when running ./configure in console in tesseract-3.05.01 folder.
Need to know, where the issue is.
The configure script uses pkg-config to see if the leptonica libs are installed (and have the required version).
After you have compiled and installed leptonica from source code you have to manually tell pkg-config where to find the lept.pc config file which is installed with leptonica. Set the PKG_CONFIG_PATH environment variable so it points to the location of lept.pc. If you installed leptonica to its default location you should do:
$ export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/
before running configure for tesseract.
Mine would not work until I did the following copy commands. My Leptonica was installed in the leptonica-1.83.0 directory, yours may be different.
cp /usr/local/leptonica-1.83.0/lib/pkgconfig/lept.pc /usr/lib64/pkgconfig/
cp -a /usr/local/leptonica-1.83.0/lib/liblept /usr/lib64
Also set:
export PKG_CONFIG_PATH=/usr/local/leptonica-1.83.0/lib/pkgconfig
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/leptonica-1.83.0/lib
export LIBLEPT_HEADERSDIR=/usr/local/leptonica-1.83.0/include/leptonica
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/leptonica-1.83.0/lib/pkgconfig
export PKG_CONFIG_PATH=/usr/local/leptonica-1.83.0/lib/pkgconfig/
Then it worked.
I am trying to install setuptools 20.4 or greater as it is a requirement for CKAN. I have tried downloading the rpm files and installing it but CKAN does not recognize the python2 rpm.
I am running a virtualenv for the ckan server under use ckan with the bash shell.
Does anybody have advice on how to properly install setuptools 20.4 or greater on centos?
If not using pip to upgrade setuptools, install/upgrade setuptools before you create the virtualenv.
I believe the rpm will update the system python's setuptools. When you create the virtualenv it copies the system setuptools into the virtualenv.
I had to update python to version 2.7.13 and then download setuptools from the python repository. Centos doesn't have official support for any python above 2.7.5 which is problematic as I have to add exclusions to yum update. Ckan does require setuptools installed this is not optional, on install it is listed as a critical error.
I have tried pip install psycopg2 and following errors i got:

Then I thought ok I should try to import and then I got this error:

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
