[Fixed] ModuleNotFoundError: No module named ‘numpy’
◈ Overview
If you are someone like me who works with lots and lots of data, then Import Error: No module named ‘xyz’ is probably one of the most common errors that you have come across. In this article, I will discuss the causes and solutions to this error in Python.
Output:
➥ Reasons of Import Error: No module Named ‘xyz’
Two major reasons that lead to the occurrence of this error:
◈ Solution
Let us dive into the probable solutions to our problem.
❋ Method 1: Fixing Faulty Installation
Note:
To resolve this issue, you can use the following command in your terminal to ensure that the latest version of Numpy is installed:
pip3 install numpy
Let’s have a look at the following graphic to visualize the solution.
❋ Method 2: Fixing Missing Path
Sometimes, even the above procedure does not work. Whenever you import a module, python searches the module in specific directories.
To get hold of all the directories that Python will search, you can use piece of code:
Ошибка импорта: нет модуля с именем numpy
У меня очень похожий вопрос к этот вопрос, но все еще на шаг позади. У меня есть только одна версия Python 3, установленная на моем Windows 7 (жаль) 64-разрядная система.
Я получил следующую ошибку:
ошибка импорта: нет модуль с именем и NumPy
Я знаю, что это, вероятно, супер основной вопрос, но я все еще учусь.

поддержка Python 3 была добавлена в NumPy версии 1.5.0, поэтому для начала вы должны загрузить / установить более новую версию NumPy.
Вы можете просто использовать
или для python3 используйте
Я думаю, что что-то не так с установкой numpy. Вот мои шаги, чтобы решить эту проблему.
просто добавьте этот комментарий в список здесь, если другие люди, как я, приходят на эту страницу с тем же сообщением об ошибке и имеют ту же проблему, что и я.
вы установили версию Numpy для Python 2.6-поэтому вы можете использовать ее только с Python 2.6. Вы должны установить Numpy для Python 3.x, например: http://sourceforge.net/projects/numpy/files/NumPy/1.6.1/numpy-1.6.1-win32-superpack-python3.2.exe/download
У меня тоже была эта проблема после установки Numpy. Я решил это, просто закрыв интерпретатор Python и снова открыв его. Если у кого-то еще есть эта проблема, возможно, это сэкономит несколько минут!
1) пожалуйста, установите numpy через командную строку (в windows) 2)Перейдите в папку Scripts и введите следующую команду
C:\Python27\Scripts>pip установить numpy
установка начинается как ниже: Сбор и NumPy Скачивание numpy-1.13.3-2-cp27-none-win32.whl (6,7 МБ) 100% |################################| 6.7 Мб 112кб/с Установка собранных пакетов: numpy Успешно установлен numpy-1.13.3
Я не уверен, почему я получаю эту ошибку, но pip3 uninstall numpy затем pip3 install numpy решил проблему для меня.
для установки NumPy через Anaconda (используйте команды ниже):
Я тоже столкнулся с вышеуказанной проблемой с phyton 3 при настройке python для машинного обучения.
установить python-2.7.13.компания MSI
установки numpy: очко установите numpy-1.13.1+mkl-cp27-cp27m-win32.whl
установка scipy: pip установить scipy-0.18.0-cp27-cp27m-win32.whl
попробовав много предложений с разных сайтов и подобных вопросов, мне удалось удалить все материалы Python и переустановить только Anaconda (см. https://stackoverflow.com/a/38330088/1083292)
предыдущая установка Python у меня была не только избыточной, но и вызвала у меня проблемы.
Solved: ModuleNotFoundError No module named «numpy» in Python3
It is not very uncommon for Python Programmers or Researchers to get the error «ModuleNotFoundError No module named ‘numpy'» while trying to run their python program. It usually happens when you forgot to install the numpy module or you are not aware of the steps to install this module. Well in both cases you need to certainly install the numpy module to run your python program. I will explain you the different methods that can be used to install numpy module in your Linux box.
What is Numpy
Numpy is a very important Python module required for the implementation of multi dimensional arrays, Linear algebra, matrices and other powerful Scientific Computations. This library is very frequently used in the field of Engineering and Scientific Research by Scientists and Researchers.
Solved: ModuleNotFoundError No module named ‘numpy’ in Python3
It is worth mentioning here that this command requires you to have python3 already installed in your Server. So if it is not installed then you can check How to Install Python3 on CentOS 7 article to know more about the installation steps. Once the module is installed if you again try to run your program you should not see any «ModuleNotFoundError No module named ‘numpy'» error again.
Another important method that you can use to install numpy module is through pip3.6 tool for python3. It is a python installer package used for managing python programs and modules. You can use pip3.6 install numpy command to install numpy module on Linux servers. Like numpy module, you can install other python modules as well by using pip3.6 install
If you want to uninstall numpy module then you can do it by using pip3.6 uninstall numpy command as shown below. Similarly if you want to uninstall any other python modules using pip3.6 utility then you need to use pip3.6 uninstall
command. So you can use pip3.6 tool for installation as well as for uninstallation of python modules. More can be checked on pip Official Documentation.
Hopefully this article helped you solving «ModuleNotFoundError No module named ‘numpy'» error.

I have installed numpy to use it in a project (using pip), but the import fails with the error «ModuleNotFoundError: No module named ‘numpy.core._multiarray_umath'». To rule out program issues, I’ve just started an interactive python3 shell and typed «import numpy», this is what I get:

Do you have multiple python version installed? And what was the command line you used to install using pip?
iacchi commented Dec 10, 2020
There are two versions of python installed, one from the Synology package, one from the Entware one. The one in the system path is the Entware one (at least, that’s the result of the command which python ), and this is all done using the Entware package. Python was installed with opkg (the Entware equivalent of linux package managers) and the same for pip. For numpy I did the usual «pip install numpy». Also, Synology’s python package doesn’t provide pip, so I’m 100% sure the pip I used is the one from Entware.

@charris I think I’m using the right python:
The python version installed by Entware is 3.9, the Synology one is 3.8.2.

I installed the lxml package with pip and then loaded it without any issue:
I copied _multiarray_umath.cpython-39-x86_64-linux-gnu.so to _multiarray_umath.cpython-39.so in the same directory and when I tried to import numpy again the error changed (the same if I put the second in place as a symbolic link rather than a copy):
And here I get a bit lost (also, I don’t want to start linking a thousand files). What should I do? Provided there is some problem with Entware’s python/pip installation, what should I report to the Entware people exactly so they can fix it?

[Solved] No Module Named Numpy in Python
Python has many external modules which are helpful to manage data efficiently. Numpy is one of those modules to handle arrays or any collection of data with ease. With many available methods, you can directly modify and edit the data according to your need. Even many universities, teach numpy as a part of their programming course. But many times, the users face, No Module Named Numpy Error. In this post, we’ll have a look at the causes and solutions for this error.
No Module Named Numpy is one of the persistent errors if you have multiple pythons installed or a virtual environment set up. This error mainly arises due to the unavailability of files in the Python site-packages. This error is easily solved by installing numpy in your working environment. But as installing numpy in the working environment is a tricky job, this error is one of the most irritating ones.
What is No Module Named Numpy?
Whenever an external module (numpy) is imported in python, it checks the package in the site packages folder if it’s available. If not, then ImportError No Module Named Numpy is raised. Moreover, if your local files in your directly have numpy.py, it can cause these issues too.
Although fixing this error requires a simple command to be used, it still can harass programmers if they are using a virtual environment. In the following section, we’ll learn about why this error is generated and the causes for it.
Why do I get No Module Named Numpy?
There are known reasons for the cause of this error. The most observed reason is due to the unavailability of Numpy in your working directory. But that’s not it, if your python file is named numpy.py, it can throw this error too. So the question arises –
Am I the only one facing this error?
No, thousands of programmers face this error either due to their IDE’s environment or they just haven’t installed Numpy.
Causes for No Module Named Numpy
As we mentioned earlier, there are some known causes for this No Module Named Numpy error to appear. Some of them are due to your mistake and some of them are not. Following are the most probable cause of this error –
Numpy Not Installed
Can you run games without installing them? No. Similarly, to use the numpy in your python program, you need to install it first. Numpy is not included in your build-in modules for python. As a result, you need to tell the package management system (pip) to install it!
Working on different Virtual Environment
Often, many different IDEs like Jupyter Notebook, Spyder, Anaconda, or PyCharm tend to install their own virtual environment of python to keep things clean and separated from your global python.
As a result, even if you have Numpy installed in your global python, you cannot use it in your virtual environment since it has separate package management. There are different methods to install numpy on each of these IDEs, all of them are mentioned in the next section.
Solutions for No Module Named Numpy
Following are the respective solutions according to your OS or IDEs for No Module Named Numpy error –
Windows
Installing modules can be tricky on Windows sometimes. Especially, when you have path-related issues. First of all, make sure that you have Python Added to your PATH (can be checked by entering python in command prompt). Follow these steps to install numpy in Windows –
Ubuntu or Linux or Mac
Anaconda
Anaconda installs its own conda environment to run python. This environment is separated from your outside installed python and can lead to import No Module Named Numpy errors. Usually, numpy is already installed in anaconda but to install numpy again in Anaconda –
Jupyter
If you have installed Jupyter from the conda environment, it’ll use Anaconda’s virtual environment for the execution of python codes. Following is the way to install numpy in Jupyter Notebook –
VsCode
In VsCode, the Integrated Terminal uses the %PATH% of python.exe to run the python programs by default. As a result, if don’t have numpy installed in your python, it’ll throw ImportError No Module Named Numpy. Either you need to change the environment to Anaconda’s environment or install numpy on the default environment. The process to install numpy on the default environment is already mentioned in the above (Windows) section.
PyCharm
PyCharm has its own set of mini Anaconda environments. If numpy is missing in this environment, it’ll throw an error No Module Named Numpy. To install numpy in Pycharm –
No Module Named Numpy Still Not Resolved?
Tried all the above methods and still import numpy not working? Then there might be some python related issues with your computer. But don’t be sad, we’ve got a universal solution for you!
Using Google Colab for your Python Projects will prevent you to install numpy on your system. Colab has its own powerful virtual environment with thousands of modules preinstalled and numpy is one of them. Follow these steps to use Google Colab for numpy –
Some Other Child Modules Error
Numpy has many other child libraries which can be installed externally. All of these libraries look like a part of numpy, but they need to be installed separately. Following are some of the examples –
No module named numpy.core._multiarray_umath
No module named numpy.testing.nosetester
Run the following commands in your terminal to resolve this error –
No module named numpy.distutils._msvccompiler
Use Python version 3.7 to solve this error. The newer versions 3.8 and 3.9 are currently unsupported in some of the numpy methods.
