Numpy ошибка установки - Не ошибается лишь тот, кто ничего не делает!

Вы пишите что-то удивительное. numpy ставится легко и непринуждённо.

Вот пример. Windows 10, Powershell 7, Pyhton 3.9. Я делаю следующее:

Создаю venv
Активирую venv
Убеждаюсь, что python указывает внутрь venv
Запускаю python, делаю import numpy и получаю отлуп: No module named 'numpy'
Устанавливаю numpy через pip внутри venv. Никаких ошибок.
Запускаю python, делаю import numpy — работает.

На каком этапе у вас ломается? Покажите весь сценарий.

Hi @seberg and @ksunden

Run the code with no cache dir param but no success, on the first moment, looks good but the same error. Also, I already have the Anaconda, this was my first workaround for the issue, once I need python for my test on university
`C:UsersLeo>pip3 install numpy —no-cache-dir

ImportError#

In certain cases a failed installation or setup issue can cause you to
see the following error message:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy c-extensions failed. This error can happen for
different reasons, often due to issues with your setup.

The error also has additional information to help you troubleshoot:

Your Python version
Your NumPy version

Please check both of these carefully to see if they are what you expect.
You may need to check your PATH or PYTHONPATH environment variables
(see Check Environment Variables below).

The following sections list commonly reported issues depending on your setup.
If you have an issue/solution that you think should appear please open a
NumPy issue so that it will be added.

There are a few commonly reported issues depending on your system/setup.
If none of the following tips help you, please be sure to note the following:

how you installed Python
how you installed NumPy
your operating system
whether or not you have multiple versions of Python installed
if you built from source, your compiler versions and ideally a build log

when investigating further and asking for support.

Using Python from `conda` (Anaconda)#

Please make sure that you have activated your conda environment.
See also the conda user-guide.
If you use an external editor/development environment it will have to be set
up correctly. See below for solutions for some common setups.

Using PyCharm with Anaconda/conda Python#

There are fairly common issues when using PyCharm together with Anaconda,
please see the PyCharm support

Using VSCode with Anaconda/conda Python (or environments)#

A commonly reported issue is related to the environment activation within
VSCode. Please see the VSCode support
for information on how to correctly set up VSCode with virtual environments
or conda.

Using Eclipse/PyDev with Anaconda/conda Python (or environments)#

Please see the
Anaconda Documentation
on how to properly configure Eclipse/PyDev to use Anaconda Python with specific
conda environments.

Raspberry Pi#

There are sometimes issues reported on Raspberry Pi setups when installing
using pip3 install (or pip install). These will typically mention:

libf77blas.so.3: cannot open shared object file: No such file or directory

The solution will be to either:

sudo apt-get install libatlas-base-dev

to install the missing libraries expected by the self-compiled NumPy
(ATLAS is a possible provider of linear algebra).

Alternatively use the NumPy provided by Raspbian. In which case run:

pip3 uninstall numpy  # remove previously installed version
apt install python3-numpy

Debug build on Windows#

Rather than building your project in DEBUG mode on windows, try
building in RELEASE mode with debug symbols and no optimization.
Full DEBUG mode on windows changes the names of the DLLs python
expects to find, so if you wish to truly work in DEBUG mode you will
need to recompile the entire stack of python modules you work with
including NumPy

All Setups#

Occasionally there may be simple issues with old or bad installations
of NumPy. In this case you may just try to uninstall and reinstall NumPy.
Make sure that NumPy is not found after uninstalling.

Development Setup#

If you are using a development setup, make sure to run git clean -xdf
to delete all files not under version control (be careful not to lose
any modifications you made, e.g. site.cfg).
In many cases files from old builds may lead to incorrect builds.

Check Environment Variables#

In general how to set and check your environment variables depends on
your system. If you can open a correct python shell, you can also run the
following in python:

import os
print("PYTHONPATH:", os.environ.get('PYTHONPATH'))
print("PATH:", os.environ.get('PATH'))

This may mainly help you if you are not running the python and/or NumPy
version you are expecting to run.

C-API incompatibility#

If you see an error like:

RuntimeError: module compiled against API version v1 but this version of numpy is v2

You may have:

A bad extension “wheel” (binary install) that should use
oldest-support-numpy (
with manual constraints if necessary) to build their binary packages.
An environment issue messing with package versions.
Incompatible package versions somehow enforced manually.
An extension module compiled locally against a very recent version
followed by a NumPy downgrade.
A compiled extension copied to a different computer with an
older NumPy version.

The best thing to do if you see this error is to contact
the maintainers of the package that is causing problem
so that they can solve the problem properly.

However, while you wait for a solution, a work around
that usually works is to upgrade the NumPy version:

pip install numpy --upgrade

Segfaults or crashes#

NumPy tries to use advanced CPU features (SIMD) to speed up operations. If you
are getting an “illegal instruction” error or a segfault, one cause could be
that the environment claims it can support one or more of these features but
actually cannot. This can happen inside a docker image or a VM (qemu, VMWare,
…)

You can use the output of np.show_runtime() to show which SIMD features are
detected. For instance:

>>> np.show_runtime()
WARNING: `threadpoolctl` not found in system! Install it by `pip install 
threadpoolctl`. Once installed, try `np.show_runtime` again for more detailed
build information
[{'simd_extensions': {'baseline': ['SSE', 'SSE2', 'SSE3'],
                      'found': ['SSSE3',
                                'SSE41',
                                'POPCNT',
                                'SSE42',
                                'AVX',
                                'F16C',
                                'FMA3',
                                'AVX2'],
                      'not_found': ['AVX512F',
                                    'AVX512CD',
                                    'AVX512_KNL',
                                    'AVX512_KNM',
                                    'AVX512_SKX',
                                    'AVX512_CLX',
                                    'AVX512_CNL',
                                    'AVX512_ICL']}}]

In this case, it shows AVX2 and FMA3 under the found section, so you can
try disabling them by setting NPY_DISABLE_CPU_FEATURES="AVX2,FMA3" in your
environment before running python (for cmd.exe on windows):

>SET NPY_DISABLE_CPU_FEATURES="AVX2,FMA3"
>python <myprogram.py>

By installing threadpoolctl np.show_runtime() will show additional information:

...
{'architecture': 'Zen',
  'filepath': '/tmp/venv3/lib/python3.9/site-packages/numpy.libs/libopenblas64_p-r0-15028c96.3.21.so',
  'internal_api': 'openblas',
  'num_threads': 24,
  'prefix': 'libopenblas',
  'threading_layer': 'pthreads',
  'user_api': 'blas',
  'version': '0.3.21'}]

If you use the wheel from PyPI, it contains code from the OpenBLAS project to
speed up matrix operations. This code too can try to use SIMD instructions. It
has a different mechanism for choosing which to use, based on a CPU
architecture, You can override this architecture by setting
OPENBLAS_CORETYPE: a minimal value for x86_64 is
OPENBLAS_CORETYPE=Haswell. This too needs to be set before running your
python (this time for posix):

$ OPENBLAS_CORETYPE=Haswell python <myprogram.py>

Одна распространенная ошибка, с которой вы можете столкнуться при использовании Python:

Import error: no module named ' numpy '

Эта ошибка возникает, когда Python не обнаруживает библиотеку NumPy в вашей текущей среде.

В этом руководстве представлены точные шаги, которые вы можете использовать для устранения этой ошибки.

Шаг 1: pip установить numpy

Поскольку NumPy не устанавливается автоматически вместе с Python, вам нужно будет установить его самостоятельно. Самый простой способ сделать это — использовать pip , менеджер пакетов для Python.

Вы можете запустить следующую команду pip для установки NumPy:

pip install numpy

Для python 3 вы можете использовать:

pip3 install numpy

В большинстве случаев это исправит ошибку.

Шаг 2: Установите пип

Если вы все еще получаете сообщение об ошибке, вам может потребоваться установить pip. Используйте эти шаги , чтобы сделать это.

Вы также можете использовать эти шаги для обновления pip до последней версии, чтобы убедиться, что он работает.

Затем вы можете запустить ту же команду pip, что и раньше, чтобы установить NumPy:

pip install numpy

На этом этапе ошибка должна быть устранена.

Шаг 3: проверьте версию NumPy

После успешной установки NumPy вы можете использовать следующую команду для отображения версии NumPy в вашей среде:

pip show numpy

нашел инструкцию, нада сначала установить пакет wheel, затем перейти в папку где лежит numpy.whl , и прописать pip install numpy.whl . Но всё равно выдает ошибку. Как с этим боротся ?

Swartex, возможно ты не правильно пишешь название .whl файла, возможно запускаешь комманду не из той папки где находится этот файл. Эти 2 варианта не подойдут — предложу еще пару

а питон вы себе поставили версии х32. Качать вам нужно файлик numpy‑1.9.2+mkl‑cp35‑none‑win32.whl . И да — изменять имя файла не нужно.
