You are using pip version 7.1.2, however version 8.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
We are well aware of this problem and are currently trying to resolve it with authors of smart_open (which we require through gensim - one of our dependencies). The problem occurs since gensim cannot be installed with environment variable LC_ALL=C which is how we install add-ons. Currently, I would suggest to install it through the terminal. On a Mac this can be done by going to Orange's installation folder and running the pip install:
cd /Applications/Orange3.app/Contents/MacOS
./pip install Orange3-Text
Beware that Orange3-Text is still in development and some major changes are coming through the summer. So if you encounter any issues, please report them on our issue tracker.

I've tried to build and run like their instructions say in that code block to the same error. I've looked around and nobody has seemingly found the fix yet, but those things are two months old usually. What am I missing?
This issue is due to a mismatch between the libffi header version and the version of libffi the dynamic linker finds. In general it appears users encountering this problem have homebrew libffi installed and have a Python built against that in some fashion.
When this happens cffi (a cryptography dependency) compiles, but fails at runtime raising this error. This should be fixable by passing the right path as a linker argument. To reinstall cffi you should pip uninstall cffi followed by
LDFLAGS=-L$(brew --prefix libffi)/lib CFLAGS=-I$(brew --prefix libffi)/include pip install cffi --no-binary :all:
This is an ugly workaround, but will get you past this hurdle for now.
Update: I've uploaded arm64 wheels for macOS so the below compilation is no longer required if your pip is up-to-date. However, if, for some reason you wish to compile it yourself:
LDFLAGS="-L$(brew --prefix openssl#1.1)/lib" CFLAGS="-I$(brew --prefix openssl#1.1)/include" pip install cryptography
I'm using Macbook Pro M1 2020 model and faced the same issue. The issue was only with my cffi and pip versions maybe. Because these 4 steps helped me -
Uninstalling old cffi pip uninstall cffi
Upgrading pip python -m pip install --upgrade pip
Reinstalling cffi pip install cffi
Intalling cryptography pip install cryptography
Probably, you'll have a problem with more packages and each has it's own solution for Apple Silicon, it's exhausting.
I came to final solution: using x86_x64 Homebrew which installs x86 packages, including Python. Thus, all your requirements are installing as on the x86_x64 macs and there are no more problems with the compilation errors and so on.
Instructions:
Run iTerm2 (or default Terminal app) under Rosetta 2 (right click on the app icon -> Get info -> Open using rosetta).
Install homebrew as usual /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" or you can get this link from https://brew.sh/ for security reasons (never copy curl commands from stackoverflow without double-checking).
Add an alias in your ~/.zshrc (if you're using ZSH) or ~/.bash_profile (if you're bash user): alias brew='arch -x86_64 /usr/local/bin/brew'.
Turn off Open using rosetta in iTerm2 Get info.
Now, every time you'll print brew in terminal apps you'll run x86_x64 Homebrew. And when you install any package from brew, it'll work under Rosetta 2 automatically.
A little late to the party, but the solutions above didn't work for me. Paul got me on the right track, but my problem was that pyenv used the mac libffi for its build and cffi used the homebrew version. I read this somewhere, can't claim this unique insight.
My solution was to ensure that my python (3.8.13) was built by pyenv using the homebrew libffi by ensuring correct headers libraries and package config:
export LDFLAGS="-L$(brew --prefix zlib)/lib -L$(brew --prefix bzip2)/lib -L$(brew --prefix openssl#1.1)/lib -L$(brew --prefix libffi)/lib"
export CPPFLAGS="-I$(brew --prefix zlib)/include -I$(brew --prefix bzip2)/include -I$(brew --prefix openssl#1.1)/include -I$(brew --prefix libffi)/include"
export PKG_CONFIG_PATH="$(brew --prefix openssl#1.1)/lib/pkgconfig:$(brew --prefix libffi)/lib/pkgconfig"
rebuilding python...
pyenv uninstall 3.8.13
pyenv install 3.8.13
killing the pip cache
pip cache purge
and, finally, reinstalling my dependencies using pipenv
pipenv --rm
pipenv sync --dev
After these steps, I was free from the dreaded
ImportError: dlopen(/private/var/folders/k7/z3mq67_532bdr_rcm2grml240000gn/T/pip-build-env-apk5b25z/overlay/lib/python3.8/site-packages/_cffi_backend.cpython-38-darwin.so, 0x0002): symbol not found in flat namespace '_ffi_prep_closure'
This answer here worked like a charm! #paveldroo
As an extension to the answer above, I went ahead and saved the alias in step 3 as alias ibrew='arch -x86_64 /usr/local/bin/brew' at ~/.zshrc
This means when I install anything with brew command, it gets installed for M1 architecture, and when I install with ibrew command it gets installed for -x86_64 architecture.
As a consequence, I installed two instances of python3 at my system one at /opt/homebrew/bin/python3 using brew and the other at /usr/local/bin/python3 using ibrew
The two versions adds some flexibility on creating the project virtual environments as needed. For example you could create virtual environments using:
/usr/local/bin/python3 -m venv venv for -x86_64 architecture
/opt/homebrew/bin/python3 -m venv venv for M1 architecture
I wasn't able to previously install cffi, until I discovered an unrelated issue. I was at this for about two days, until I found this command:
python3 -m ensurepip --upgrade
Magically, everything started working for me. It came from an issue between Python and Pip coming from different sources.
Answer stolen from this question: using pip3: module "importlib._bootstrap" has no attribute "SourceFileLoader"
Edit: This may be a courtesy of the above poster, so could be unrelated. If so, thank you anonymous human!
I have uninstalled older version of cffi and cryptography,
pip uninstall cffi
pip uninstall cryptography
and updated the requirements.txt file from exact versions to updated versions
# requirements.txt
cffi>=1.15.1
cryptography>=38.0.1
(version number can be different).

It seems that scikit-learn has not been built correctly.
If you have installed scikit-learn from source, please do not forget
to build the package before using it: run `python setup.py install` or
`make` in the source directory.
It appears that you are importing a local scikit-learn source tree. For
this, you need to have an inplace install. Maybe you are in the source
directory and you need to try from another location.

If you've installed a package using pip3.6, make sure that your kernel version for your notebook is 3.6 -- if it's (say) 3.7, then it won't work, because each version of Python has its own separate set of installed modules.
I imported the notebook, and forgot to change Kernel Python3.6. It was still on Python3. Changed notebook to 3.6, and the it used the updated libary's-
When you run pip on PythonAnywhere, outside virtual environment, it installs packages for python2. The latest version of scikit-learn to work with python2 is 0.20.4. So, install it with pip install scikit-learn==0.20.4

Edit 1:
I have also added my PostgreSQL path to system path variables

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.

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:

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.
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

(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.
