看來我的點子壞了：
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.

為什么我不能卸載numpy？
編輯：不確定它是否相關，但我安裝了 OpenVINO
EDIT2：我嘗試了建議的解決方案，但它不起作用：
ubuntu@ip-x:~$ pip3 install --force-reinstall --no-deps numpy==1.19.5

EDIT3：我正在嘗試安裝，因為我在使用 numpy 時遇到了一些問題。我認為有不同的版本，比較：
pip3 uninstall numpy

uj5u.com熱心網友回復：
因為你的 numpy 安裝要么壞了，要么沒有被 pip 處理：
ERROR: Cannot uninstall numpy 1.19.5, RECORD file not found.
要么采用提供的蠻力解決方案，要么追蹤 numpy 檔案的實際來源——看看你的 PYTHONPATH。
uj5u.com熱心網友回復：
最終的解決方案是直接洗掉 numpy
rm -rf ~/.local/lib/python/site-packages/numpy
pip install numpy
但首先你應該檢查你使用哪個 python 并找到你的站點包路徑
uj5u.com熱心網友回復：
看來我修復了：
pip3 install --user --force-reinstall --no-deps numpy==1.19.5
至少這讓 numpy 和 numba 作業。
uj5u.com熱心網友回復：
- 您可以使用此命令查找已安裝的軟體包
pip freeze - 我建議你使用虛擬環境
