Error failed building wheel for numpy failed to build numpy

The wheel is a distribution or packaging format that utilizes a file with the extension “.whl” to save the necessary metadata and files for installing a package.

The wheel format is designed to make it easier to install packages and can be used as an alternative to the traditional source distribution format (.tar.gz) or built distribution format (.egg).

The wheel file includes all the required information and resources to successfully install the package, including package dependencies and compiled binaries, if applicable.

The error: failed building wheel for numpy occurs when you try installing the Python package `numpy`. The error occurs because either you are using Python outdated, or pip outdated, or some dependencies need to be installed on your machine.

How to Fix Error: failed building wheel for numpy

Five easy ways to fix the error: failed building wheel for numpy in Python.

1. Ensure that you are using the latest `pip` version.
2. Install the numpy library with –no flag.
3. Try installing a different version of numpy.
4. Install the necessary build tools and dependencies.
5. Uninstall and reinstall numpy.

Solution 1: Use the latest version of the pip

To upgrade pip in Python, install the below command.

python3 -m pip install --upgrade pip

Ensure that you have the latest version of the pip package manager.

Solution 2:  Install numpy with –no flag

Try installing numpy with the –no-binary flag.

python3 -m pip install --no-binary numpy numpy

Solution 3:  Install a different version of numpy

You can install different versions of numpy to see if any version is compatible with your current Python environment.

To install the specific version of Numpy, use the below command.

python3 pip install numpy==1.24.0

Solution 4: Install the necessary dependencies

Numpy requires a C compiler, such as GCC, and the Python development headers.

To install On Ubuntu(Type of Linux OS), install these dependencies with the following command.

sudo apt-get install build-essential python-dev

Solution 5: Uninstall and reinstall the numpy library

If none of the above solutions work, the last stop is to uninstall any previous version or part of it from your system and reinstall the numpy from scratch.

To uninstall numpy:

python3 -m pip uninstall numpy

To install numpy:

python3 -m pip install numpy

It will install the latest version of numpy.

Conclusion

The best way to solve the error: failed building wheel for numpy is to check the current version of pip and Python and check if they are compatible with the current version of the Python environment. If anything is outdated, then upgrade everything to the latest version and then try to install numpy again.

error: failed building wheel for numpy ( Solved )

Numpy Array Equal Method : How to check if numpy arrays are equal

Numpy is the best python package for array creation and computing complex mathematic calculations. Generally, you are able to install NumPy easily using the pip command. But sometimes you are unable to install it and get the error message failed building wheel for numpy. In this entire tutorial, you will know why this error comes and how to solve the error: failed building wheel for NumPy error.

What is a Wheel?

The wheel is a distribution or packaging format. Today most coders use it for building and packaging the python code. There is a file of the format WHL that saves the packaging information in wheel format. The Wheel contains all the metadata and files for the python to install the package.

What causes error: failed building wheel for NumPy error

Most of the time this type of error comes when there is a NumPy version released. The current NumPy releases do not support the specific python version. So the wheel format file is unable to install the version of the Numpy in your system. And it causes the failed building wheel for numpy error.

Solution for the failed building wheel for NumPy

The solution for the error failed building wheel for NumPy is very simple. I will discuss different ways to solve this type of error.

Solution 1: Upgrade the pip

The first solution to remove this error is to first upgrade the pip command. After upgrading try to install the NumPy version using the pip command.

But make sure to check the version of the python. If the version is 3. xx then use the pip3 command and if it is 2. xx then use the pip command.

Use the below command to check the version of python. Checking the Python version before installing spacy

Use the below command to install the NumPy.

For python3.xx

For python 2. xx

My system has python 3. xx so I will use the pip3 command. Install numpy using the pip3 command

Solution 2: Install the specific NumPy version

If you are still getting the error after applying solution 1 then you have to check which version of the Numpy is supported by the python. In this case, you have to downgrade the NumPy version.

For example, let’s say the current Numpy version is 1.19 and it is not supported by python. Then you have to check the version of the NumPy supported by the python. Let’s say it is 1.18 then you will install it using the below command. Install the specific version of numpy

It will successfully install the NumPy and you will not get the failed building wheel for NumPy.

Conclusion

Numpy is a great package if you want to do computational work on datasets. These are the ways that can solve the error.

ERROR: Failed building wheel for reedsolo #32

Unexpected behaviour

pip install reedsolo

Expected behaviour

pip installation should run without need to install massive ms toolchain. Provide wheels?

The text was updated successfully, but these errors were encountered:

I am using WinPython distributions for all of my windows machines:
https://winpython.github.io/
I suspect something is broken with this particular WinPython version.
I just tried it on another computer with (Win)Python 3.7.7, there pip install —upgrade reedsolo worked without errors.
I will have another look at the other machine with (Win)Python 3.8.6. and report back.

Still after switching from WinPython 3.8.6.0 to WinPython 3.8.8.0 on this machine, i had no success to install reedsolo .

Only after installing the latest Microsoft Visual C++ 14.2 Build Tools on this machine I was able to install reedsolo without any error messages.

I think that issue can be closed with this.

I still wondered why a ready-made wheel is not taken instead.
Could it be because only one wheel is provided for Python 3.7?

Only after installing the latest Microsoft Visual C++ 14.2 Build Tools on this machine I was able to install reedsolo without any error messages.

I think that issue can be closed with this.

The problem with this solution is it requires installing a 6.8GB build tool. Pip should provide a compiled binary avoiding the need for it.

edit: found a solution: pip install reedsolo —no-binary=

To answer both of your questions, I GUESS (but I’m not sure) that you both had Cython installed but without a C compiler compatible with your Python version. So reedsolo tried to compile on pip install but failed miserably.

But note that there IS a compiled binary in the wheel, that’s why I went through the hassle of configuring a quite complex setup.py to manage different cases. But Python is NOT a language made for compilation, so this kind of use case is a bit off limits, and errors like this can happen. Maybe now with pip3 it works better, fairly complex tools are now installable with pip instead of requiring precompiled binaries through conda or other recipe forges, but I don’t have the time to rework everything.

I have merged some proposed changes to fix this issue hopefully. Please let me know if it now works (I know it’s quite late, but it’s all pro-bono voluntary work here, and it’s not even my specialty field).

Please re-open this thread if necessary. Thank you for your patience.

BUG: Failed building wheel for numpy in Python 3.10 #20039

Describe the issue:

I have download the new Python 3.10 and tried to run some code.
When trying to update numpy, the following message appears:
Failed to build numpy
ERROR: Could not build wheels for numpy which use PEP 517 and cannot be installed directly
I have also done a search for a similar bug report and I found out that it was happening since Python 3.9:
#17569

Reproduce the code example:

NumPy/Python version information:

Python 3.10.0
Numpy 1.21.2

The text was updated successfully, but these errors were encountered:

I removed part of the error report and left the important part: something is missing in your Visual Studio installation to build NumPy. In any case, you would get a subpar experience without using an OpenBLAS library like in our binary wheels.

The solution for this, like the solution for this issue you linked to, is to wait a month or so until binary wheels are available for python 3.10.

Same error when trying to install Pandas. I have installed Wheel and Numpy already.

You can still install pandas on 3.10 tho, but you need to install it from the source instead of using pip.

same with Poetry :S

NumPy/Python version information:

Python 3.10.0 Numpy 1.21.2

What version of wheel are you using? We pin wheel because of the changes upstream. At some point in the next year or two we will switch to another build system.

I found a possible solution. I had to install the visual c++ runtime build tools so it would build the npymath module. Then the pip install numpy went as expected. Windows 10, latest python as of Oct 2021.

I don’t think I had any of the visual c++ build tools on this computer.

I’m having the same issue. Is there any way to update it manually, not through console?

Same error when trying to install Pandas. I have installed Wheel and Numpy already.

ERROR: Failed building wheel for numpy Failed to build numpy ERROR: Could not build wheels for numpy, which is required to install pyproject.toml-based projects

same error, is there any perfect solution
have you found any solution.

but yeah, in older version it works so i am moving towards older version

NumPy 1.21.3 has wheels for Linux, macOS and Windows (see https://pypi.org/project/numpy/1.21.3/#files), so I will close this issue. Most of this seems to be due to people upgrading to 3.10 too early and not having the right compilers and other dependencies installed to build from source. So nothing left to do here.

Same error when trying to install Pandas. I have installed Wheel and Numpy already.

ERROR: Failed building wheel for numpy Failed to build numpy ERROR: Could not build wheels for numpy, which is required to install pyproject.toml-based projects
me too

Facing same issue, I guess the numpy wheels are still not there..

Wheels are present for 3.10. Please do not comment on an old and closed issue with zero details on your actual problems. You are likely trying to install another project which declares its dependency on numpy in an incorrect fashion. It’s easy to verify that Python 3.10 wheels are present in https://pypi.org/project/numpy/#files.

In case you do suspect an actual problem in numpy packaging, please open a new issue with a complete and reproducible description of your build/install steps (starting from how you installed Python, then the actual commands you ran, then the full traceback you are seeing).
