无法在 ubuntu 上卸载 numpy

Question

看来我的点子坏了：

ubuntu@ip-x:~$ pip3 uninstall numpy
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

为什么我无法卸载 numpy？

编辑：不确定是否相关，但我安装了 OpenVINO

EDIT2：我尝试了建议的解决方案，但它不起作用：

ubuntu@ip-x:~$ pip3 install --force-reinstall --no-deps numpy==1.19.5

EDIT3：我正在尝试安装，因为我在使用 numpy 时遇到了一些问题。我觉得有不同的版本，比较一下：

pip3 uninstall numpy
Found existing installation: numpy 1.19.5
ERROR: Cannot uninstall numpy 1.19.5, RECORD file not found. You might be able to recover from this via: 'pip install --force-reinstall --no-deps numpy==1.19.5'.

与

ubuntu@x:~$ python3 -c "import numpy;print(numpy.__version__);print(numpy.__file__)";
1.18.5
/usr/local/lib/python3.6/dist-packages/numpy/__init__.py

EDIT4：我不能使用numba：

Answer 1

因为你的 numpy 安装要么坏了，要么没有被 pip 处理：

ERROR: Cannot uninstall numpy 1.19.5, RECORD file not found.

要么采用提供的蛮力解决方案，要么追踪 numpy 文件的实际来源——查看您的 PYTHONPATH。

Answer 2

最终的解决方案是直接删除 numpy

rm -rf ~/.local/lib/python/site-packages/numpy
pip install numpy

但首先你应该检查你使用的是哪个 python 并找到你的站点包路径

Answer 3

看来我已经解决了：

pip3 install --user --force-reinstall --no-deps numpy==1.19.5

至少这让 numpy 和 numba 正常工作。

Answer 4

1. 您可以使用此命令找到已安装的软件包 pip freeze
2. 我推荐你使用virtual enviroment
