ERROR: Failed building wheel for argon2-cffi
Failed to build argon2-cffi
ERROR: Could not build wheels for argon2-cffi which use PEP 517 and cannot be installed directly
How can I build argon2-cffi successfully?

I solved it following these steps:
sudo apt install -y build-essential python3.8-dev // ubuntu 20.04
pip3 install pep517 // or python3.8 -m pip install pep517
pip3 install jupyterlab // successfully

set compile flags when installing Python + C++ project

When pip-installing a Python project with C++ parts,
pip3 install . --verbose --user
the typical compile line will be something like
x86_64-linux-gnu-gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -g -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -fPIC -I/usr/include/eigen3/ -I/usr/local/include/python3.7 -I/home/nschloe/.local/include/python3.7m -I/usr/include/python3.7m -c src/generate.cpp -o build/temp.linux-x86_64-3.7/src/generate.o
Explicitly setting CFLAGS like
OPT="" CFLAGS="" pip3 install . --verbose --user
results in
x86_64-linux-gnu-gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -Wdate-time -D_FORTIFY_SOURCE=2 -fPIC -I/usr/include/eigen3/ -I/usr/local/include/python3.7 -I/home/nschloe/.local/include/python3.7m -I/usr/include/python3.7m -c src/generate.cpp -o build/temp.linux-x86_64-3.7/src/generate.o
retaining most of the flags.
Question: Where are all the compiler options set? More specifically: How can I remove -g? (It's eating too much memory.)

CC for python distutils to build c

I was trying to build c through python distutils. I want to replace CC with gcc and follow this page
CC=gcc python setup.py build
Then I got
gcc -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fno-strict-aliasing -Wdate-time -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security -fPIC -I/usr/include/python2.7 -c hello.c -o build/temp.linux-x86_64-2.7/hello.o
creating build/lib.linux-x86_64-2.7

CC only changed to gcc on first stage, and it would become original x86_64-linux-gnu-gcc, I am not sure is there anything missing, thanks.

You must set "CC" with
os.environ["CC"] = "GCC"
However, this sometimes does not work in windows and involves some changes in the config files.
Create file "C:\Python27\Lib\distutils\distutils.cfg" and write this inside
Then insert the following code:
[build]
compiler = gcc
Remove all instances of "-mno-cygwin" gcc option from file "C:\Python27\Lib\distutils\cygwinccompiler.py":
In the same file convert this:
self.set_executables(compiler='gcc -mno-cygwin -O -Wall',
compiler_so='gcc -mno-cygwin -mdll -O -Wall',
compiler_cxx='g++ -mno-cygwin -O -Wall',
linker_exe='gcc -mno-cygwin',
linker_so='%s -mno-cygwin %s %s'
% (self.linker_dll, shared_option,
entry_point))
to this:
self.set_executables(compiler='gcc -O -Wall',
compiler_so='gcc -mdll -O -Wall',
compiler_cxx='g++ -O -Wall',
linker_exe='gcc',
linker_so='%s %s %s'
% (self.linker_dll, shared_option,
entry_point))

I found the answer here, LDSHARED is the variable I need.
The full command would be like this
CC=gcc LDSHARED=gcc -pthread -shared python setup.py build

I tried every solution I found so far and none seemed to work, has anyone any idea about this problem, please? Thank you

Run into the same issue and solved with:
yum install openmpi-devel
export CC=/usr/lib64/openmpi/bin/mpicc
pip install mpi4py

it seems you missed to install the development files of OpenMPI on Centos, the line that is the key here is:
_configtest.c:2:17: fatal error: mpi.h: No such file or directory
#include <mpi.h>
you should install the openmpi-devel (or equivalent) through yum and you should be good to reinstall the mpi4py module.

You could also try:
CentOS
yum install python-mpi4py
yum install python3-mpi4py
Debian
apt install python-mpi4py
apt install python3-mpi4py

For anyone else who runs into this, I'm posting this answer just in case you have a similar problem to me. The answer from #francis was the key. On my Centos7.7 system I was able to install mpi4py using the CC environment variable suggested by #iakov-nakhimovski but it was not working and I was getting runtime errors. The problem turned out to be that other software installed on the system had its own python installation in the path which was interfering with the setup of mpi4py. The solution was to remove this other installation from the path and to load the openmpi module which was shipped with the openmpi-devel package (I think).
module load mpi/openmpi-x86_64
Then install mpi4py using pip (note you do not need to explicitly define CC=mpicc since all these tools get put into the path by the environment module). When running a python script which requires mpi4py you also need to load this module.

How to install polyglot on Raspberry Pi? - problems with compatibility

I want to install this on my Raspberry Pi 2 (Raspbian):
http://polyglot.readthedocs.org/en/latest/Installation.html
Unfortunately, when I did sudo pip install polyglot I got the following error:

I believe this is a problem with PYCLD2? It is for 64bit system?
How to solve this problem?

After executing: sudo apt-get install python-dev
I got:

I managed to solve this problem.
First you need to do is to download polyglot's source code:
git clone https://github.com/aboSamoor/polyglot
Then edit setup.py:
nano polyglot/pycld2/setup.py
Change this line:
extra_compile_args=['-w', '-O2', '-m64', '-fPIC'],
to:
extra_compile_args=['-w', '-O2', '-fPIC'],
Install PYCLD2:
sudo ./setup.py install
Install polyglot:
cd ..
sudo ./setup.py install
