Sure, to collect numpy, you can use the following command in Python:
```python
pip install numpy
```
This will install the numpy package, which is a powerful library for numerical computing in Python. It provides support for large, multi-dimensional arrays and matrices, along with a collection of mathematical functions to operate on these arrays efficiently.

pip 下载的时候 出现 collecting numpy 就没了 也没有报错
这种情况可能是因为 pip 已经自动安装了 numpy 或者已经存在了适合您系统的 numpy 版本,所以没有再次下载。您可以通过以下方法来确认是否已经安装了 numpy:
1. 打开命令行终端(Windows 用户可以通过按下 Win+R 并输入 cmd,然后按下 Enter 打开)。
2. 输入 `python` 并按下 Enter 进入 Python 解释器。
3. 在解释器中输入 `import numpy` 并按下 Enter。
4. 如果没有错误提示,说明 numpy 已经安装成功。
如果您需要确认已经安装的 numpy 版本是否适合您的需求,可以在 Python 解释器中输入 `numpy.__version__` 获取当前 numpy 版本号。如果需要安装其他版本的 numpy,可以通过 `pip install numpy==版本号` 的方式进行安装。
Collecting numpy Could not find a version that satisfies the requirement numpy (from versions: ) No matching distribution found for numpy
This error occurs when the version of `pip` you are using is outdated or the package index is not up-to-date. You can try the following steps to resolve the issue:
1. Upgrade `pip` by running `pip install --upgrade pip`.
2. Try installing `numpy` again by running `pip install numpy`.
3. If step 2 fails, you can try updating the package index by running `pip install --upgrade setuptools`.
4. Try installing `numpy` again.
If none of the above steps work, you can try installing `numpy` using a binary distribution specific to your operating system. You can find the appropriate binary distribution for your operating system on the official `numpy` website.
