NumPy（Numerical Python ）是^{(Numerical Python)}Python编程语言的开源库。它用于科学计算和使用数组。除了它的多维数组对象外，它还提供了用于处理数组的高级功能工具。在这篇文章中，我们将引导 您了解如何在 Windows 10 上使用PIP安装^(PIP)NumPy 。

与大多数 Linux 发行版不同，Windows默认不附带Python编程语言。

要在Windows 10上使用Pip安装NumPy，首先需要在 Windows 10 PC 上下载^(download)并安装Python 。确保为所有用户^{(Install launcher for all users)}选择安装启动器和将Python 添加到 PATH^{(Add Python to PATH)}复选框。后者将解释器置于执行路径中。

安装最新的Python后，您可以继续在Windows 10上使用Pip安装^(Pip)NumPy。

现在，如果您在Windows上使用旧版本的Python，您可能需要手动安装PIP 。Pip与Python 2.7.9+和Python 3.4+一起自动安装。

您可以通过下载^{(downloading)}安装包、打开命令行并启动安装程序轻松地在Windows上安装^(Windows)PIP 。您可以通过运行以下命令通过 CMD 提示符在Windows 10上安装^{(Windows 10)}Pip 。

python get-pip.py

您可能需要以管理员身份运行命令提示符^{(run the Command Prompt as administrator)}，如果您在任何时候收到错误提示您没有执行任务所需的权限，则需要以管理员身份打开应用程序。

Pip安装应该开始。如果找不到文件，请仔细检查保存文件的文件夹的路径。

您可以使用以下命令查看当前目录的内容：

dir

dir命令返回目录内容的完整列表。

安装Pip后，您可以通过键入以下内容来测试安装是否成功：

pip --version

如果Pip已安装，程序将运行，您应该会看到以下输出：

pip 20.1.1 from c:\users\<username>\appdata\local\programs\python\python38-32\lib\site-packages\pip (python 3.8)

现在您已确认已安装Pip，您现在可以继续安装NumPy。

^{(Install NumPy)}在Windows 10上使用PIP安装 NumPy

设置Pip^(Pip)后，您可以使用它的命令行来安装NumPy。

要使用Python 3^{(Python 3)}的包管理器安装NumPy，请运行以下命令：

pip3 install numpy

Pip下载NumPy包并通知您它已成功安装。

要在Windows上升级Pip，请在命令提示符中输入以下内容：

python -m pip install --upgrade pip

此命令首先卸载旧版本的Pip，然后安装最新版本的Pip。

安装后，您可以使用show命令验证NumPy现在是否是Python包的一部分。运行以下命令：

pip3 show numpy

输出应该确认你有NumPy，你正在使用哪个版本，以及包的存储位置。

这就是如何在Windows 10上使用Pip安装^(Pip)NumPy！

How to install NumPy using PIP on Windows 10

NumPy (Numerical Python) is an open-source library for the Python programming language. It is used for scientific computing and working with arrays. Apart from its multidimensional array object, it also provides high-level functioning tools for working with arrays. In this post, we will walk you through on how to install NumPy using PIP on Windows 10.

Unlike most Linux distributions, Windows does not come with the Python programming language by default.

To install NumPy using Pip on Windows 10, you first need to download and install Python on your Windows 10 PC. Make sure you select the Install launcher for all users and Add Python to PATH checkboxes. The latter places the interpreter in the execution path.

Once you have the latest Python installed, you can proceed to install NumPy using Pip on Windows 10.

Now, If you are using an older version of Python on Windows, you may need to install PIP manually. Pip is automatically installed with Python 2.7.9+ and Python 3.4+.

You can easily install PIP on Windows by downloading the installation package, opening the command line, and launching the installer. You can install Pip on Windows 10 via CMD prompt by running the command below.

python get-pip.py

You may need to run the Command Prompt as administrator, if you get an error at any point stating that you don’t have the necessary permissions to perform a task, you will need to open the app as admin.

Pip installation should start. If the file isn’t found, double-check the path to the folder where you saved the file.

You can view the contents of your current directory using the following command:

dir

The dir command returns a full listing of the contents of a directory.

Once you’ve installed Pip, you can test whether the installation has been successful by typing the following:

pip --version

If Pip has been installed, the program runs, and you should see the following output:

pip 20.1.1 from c:\users\<username>\appdata\local\programs\python\python38-32\lib\site-packages\pip (python 3.8)

Now that you have confirmed you have Pip installed, you can now proceed to install NumPy.

Install NumPy using PIP on Windows 10

With Pip set up, you can use its command line for installing NumPy.

To install NumPy with the package manager for Python 3, run the following command:

pip3 install numpy

Pip downloads the NumPy package and notifies you it has been successfully installed.

To upgrade Pip on Windows, enter the following in the command prompt:

python -m pip install --upgrade pip

This command first uninstalls the old version of Pip and then installs the most current version of Pip.

After the installation, you can use the show command to verify whether NumPy is now part of you Python packages. Run the following command:

pip3 show numpy

The output should confirm you have NumPy, which version you are using, as well as where the package is stored.

And that’s it on how to install NumPy using Pip on Windows 10!
