python - ERROR: Could not build wheels for scipy which use PEP 517 and cannot be installed directly

Question

I'm trying to install scipy via pip on my 64 bit ARMV8 board. I have already installed openblas which is required by scipy. So, no issues with that. When i gave pip3 install scipy --trusted-host pypi.org --trusted-host files.pythonhosted.org , I got the error Failed building wheel for scipy . I have pip3 and pip3.5 in my /usr/bin and the rest of the pip is in /usr/lib64/python3.5/site-packages.So basically, I also have pip.

I also tried to install scipy with --no-binary option, which was one of the answers on net. But, it gave me the same error. Below's the error that i got.

  ERROR: Failed building wheel for scipy
Failed to build scipy
ERROR: Could not build wheels for scipy which use PEP 517 and cannot be installed directly

Answer 1

I had the same issue with opencv-python. What worked for me was updating pip as:

pip3 install --upgrade pip

Note: I am using docker on Linux.

Answer 2

I had the same issue. I resolved this issue after run below command

pip install --upgrade pip setuptools wheel

Answer 3

My problem was not with scipy, but with xmlsec. The error message was almost the same:

ERROR: Could not build wheels for xmlsec which use PEP 517 and cannot be installed directly

I needed this library, because it was dependency for python3-saml. From the documentation I read that they first install these packages:

sudo apt-get install libxml2-dev libxmlsec1-dev

After doing this the installation of python3-saml worked for me.

pip3 -V
pip 20.2.3

python -V
Python 3.8.0b3

Probably the answer for other libraries is different, but they all need some package in order to be build, and you should find what is this package for you.

Answer 4

This error also comes for numpy and if you are using the new M1 chip, I am afraid you have to install packages like numpy differently. Check this out.

Answer 5

directly do

pip install p5py
pip install PEP517

this will do the work.

Answer 6

I faced the same problem. Seems that pip uses the pkg-config - if this is missing from your host OS it will run into this error. I resolved by:

sudo apt-get install -y pkg-config

Then re-run pip

Answer 7

In my case I was installing from a requirements.txt file with the command:

pip install -r requirements.txt

And was getting this error. I solved it installing the package individually (pip install scipy) and replacing the version of Scipy I had in requirements.txt with the one that worked.

Answer 8

If using Windows OS, verify under Start > Settings > Update & Security > Windows Security > Virus & threat protection > Protection History if Windows is identifying the file for installing PyInstaller with Pip as potential malware and thus blocking it. Worked for me.

Answer 9

Personally I get rid of this error by changing the #!/usr/bin/env python3.9 to #!/usr/bin/env python3 in the file located in ~/.poetry/bin/poetry and running pip3 install --upgrade pip setuptools wheel apparently python3.9 got some difficulties with poetry.

Answer 10

ERROR: Failed building wheel for h5py
Failed to build h5py
ERROR: Could not build wheels for h5py which use PEP 517 and cannot be installed directly

I had a similar issue while installing Keras, resolved above issue using below steps:

1. conda install h5py

2. pip install keras

Answer 11

I had the same issue and solved it by installing the module using conda. In my case conda install -c conda-forge statsmodels worked without error.
