ERROR: Could not build wheels for spacy, which is required to install pyproject.toml-based projects

Hi Guys, I am trying to install spacy model == 2.3.5 but I am getting this error, please help me!

Try using python 3.6-3.9 instead, where there are binary wheels for pip install to use instead of having to compile from source.
(This is a conflict with python 3.10 and some generated .cpp files in the source package. Python 3.10 wasn't released yet when this version was published.)

I had the similar error while executing pip install -r requirements.txt but for aiohttp module:
socket.c -o build/temp.linux-armv8l-cpython-311/aiohttp/_websocket.o
aiohttp/_websocket.c:198:12: fatal error: 'longintrepr.h' file not found
#include "longintrepr.h"
^~~~~~~ 1 error generated.
error: command '/data/data/com.termux/files/usr/bin/arm-linux-androideabi-clang'
failed with exit code 1
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for aiohttp
Failed to build aiohttp
ERROR: Could not build wheels for aiohttp, which is required to install
pyproject.toml-based projects
Just in case I will leave here solution to my error. This error is specific to Python 3.11 version. On Python with 3.10.6 version installation went fine.
To solve it I needed to update requirements.txt.
Not working versions of modules with Python 3.11:
aiohttp==3.8.1
yarl==1.4.2
frozenlist==1.3.0
Working versions:
aiohttp==3.8.2
yarl==1.8.1
frozenlist==1.3.1

https://github.com/aio-libs/frozenlist/issues/305

Try using:
!pip install spacy==2.3.5
Do not give space between == and 2.3.5
If you give any space between equal sign and version, it may give error.

Python delocate-wheel breaks wheel on MacOS

I'm generating wheel files to support a python distribution on MacOS using delocate. The wheels rely on libraries installed when gcc is installed using Homebrew.
brew install -v gcc#10
/usr/local/Cellar/gcc/10.2.0_3/lib/gcc/10/libstdc++.6.dylib
/usr/local/lib/gcc/10/libgcc_s.1.dylib
When running delocate-wheel with verbose option, the above are the two libraries included in the wheel.
If I use pip to install the original wheel, I can run the program without issue.
After running delicate-wheel and installing the new de-located wheel and trying to run, I produce this error:
python(66449,0x105ea3dc0) malloc: *** error for object 0x1071c3b60: pointer being freed was not allocated
python(66449,0x105ea3dc0) malloc: *** set a breakpoint in malloc_error_break to debug
I have tried using the require-archs=intel, but this errors out, and it appears that I only have single architecture files: Non-fat file: /usr/bin/python is architecture: x86_64
thank you,

Cannot install nlopt python module

I am trying to install nlopt onto macOS 10.15.5. I downloaded the nlopt-2.6.2.tar.gz file from the NLopt docs and ran the following from the nlopt-2.6.2 directory:
mkdir build
cd build
cmake -DNLOPT_OCTAVE=Off -DNLOPT_MATLAB=Off -DNLOPT_GUILE=Off ..
make
sudo make install
I got the following output: cmake.txt.
The header file (nlopt.h) installs correctly to /usr/local/include and the dynamic library (libnlopt.dylib) installs correctly to /usr/local/lib/, but neither the dist-info file nor the nlopt module itself installs.
I have also tried installing via pip, brew, and conda, none of which have worked. I have also tried cloning from this Github, which didn't work either.
I appreciate any help with this, because I am completely lost. I am relatively new to this kind of stuff, and I couldn't find any good answers online.

The official docs are somewhat laconic about the exact steps required for building nlopt with Python bindings. First of all, you'll need SWIG installed:
$ brew install swig
Then, you'll need numpy to be available for the target Python interpreter. It is already preinstalled for the system Python, otherwise install it via Homebrew or pip, depending on your Python installation.
Now run cmake:
$ cmake -DNLOPT_GUILE=OFF -DNLOPT_MATLAB=OFF -DNLOPT_OCTAVE=OFF -DNLOPT_TESTS=OFF
This will build bindings against the default Python 2.7 installation preinstalled on MacOS. If you need to build against custom Python installation (e.g. when you've installed Python 3 via Homebrew or PKG installer from https://www.python.org/downloads), pass it via the PYTHON_EXECUTABLE arg:
$ cmake -DNLOPT_GUILE=OFF -DNLOPT_MATLAB=OFF -DNLOPT_OCTAVE=OFF -DNLOPT_TESTS=OFF -DPYTHON_EXECUTABLE=/usr/local/bin/python3
Inspect the log now - Python, SWIG and numpy headers should be successfully located. Example output snippet (you may have different paths/versions printed):
-- Found PythonInterp: /usr/local/bin/python3.8 (found version "3.8.3")
-- Found PythonLibs: /Library/Frameworks/Python.framework/Versions/3.8/lib/libpython3.8.dylib (found suitable exact version "3.8.3")
-- Found NumPy: /Users/hoefling/Library/Python/3.8/lib/python/site-packages/numpy/core/include (found version "1.19")
-- Found SWIG: /usr/local/bin/swig (found version "4.0.2")
If any of those conditions is not satisfied (e.g. you see Could NOT find NumPy, Could NOT find PythonLibs or Could NOT find SWIG), then stop and make sure the configuration succeeds before proceeding next.
Now compile:
$ make

I'm trying to install a pysnap library from github. This is part of the output I get. I have no idea how to proceed, any help would be greatly appreciated.

What platform are you trying to install pysnap?
I downloaded and installed pysnap sucessfully from this github location
I do have windows 10 platform and python 2.7 though. I dont' have a linux to replicate this issue.
If you are trying to install on Linux, depending on flavor and its setup , sometimes swap is setup as as /tmp and some applications are not able to write to /tmp. In your case it does looks like its trying to write to /tmp and erroring out.
Can you try pip install cryptography
and see if its able to install cryptography part without issues?
Once that dependency is out of way, you can install pysnap so that pysnap will not try to install cryptography

Trouble installing Dlib for python on Mac OSX 10.10

I'm trying to install dlib-18.16 for python on my computer (running Mac OSX 10.10). I have boost python installed as well as X11, but I've been running into trouble when running ./compile_dlib_python_module.bat as instructed to after downloading the files.
The errors I get are numerous, but look something like this
[ 1%] Building CXX object dlib_build/CMakeFiles/dlib.dir/gui_widgets/fonts.o
In file included from /Users/xxx/Downloads/dlib-18.16/dlib/gui_widgets/fonts.cpp:14:

XAllocColor(d, cmap, &xcol);
This continues for a while and ends with
/Users/xxx/Downloads/dlib-18.16/dlib/gui_widgets/nativefont.h:400:21: error: use
of undeclared identifier 'XFillRectangle'
XFillRectangle(d, pix, gc, 0, 0, width, height);
^
fatal error: too many errors emitted, stopping now [-ferror-limit=]
20 errors generated.
make[2]: *** [dlib_build/CMakeFiles/dlib.dir/gui_widgets/fonts.o] Error 1
make[1]: *** [dlib_build/CMakeFiles/dlib.dir/all] Error 2
make: *** [all] Error 2
I've checked for some of the missing functions like XFillRectangle, and found them declared in some .h files in the anaconda install of python (when looking at the dlib_build files, the installer seems to have located the anaconda install). Does anyone have any ideas as to how to fix this?

I realized that I had to go into the CMakeCache.txt file and manually change the X11 path from anaconda to usr/X11, as the anaconda versions of the X11 .h files were missing some of these XQuartz functions. Everything works now.

I had this issue with the version in PyPi (19.4.0).
Installing directly from source (19.4.99) seems to work.
So something between those two versions has resolved this.
Commands to install from source:
git clone https://github.com/davisking/dlib.git
cd dlib
pip install .
FYI, here are the Xlib.h files I have on my system as the presumption is it was picking up a different version of XLib.h which didn't have these symbols.
Running on OS-X 10.11.4 with Python 2.7. I definitely have XQuartz installed.
