去www.lfd.uci.edu/~gohlke/pyt… 下载“- pandas‑1.4.3‑cp310‑cp310‑win_amd64.whl” 到本地，在下载目录安装：
pip install pandas-1.4.3-cp310-cp310-win_amd64.whl
问题二：
安装中出现下列错误：
Running setup.py install for grpcio ... error
升级pip,setuptools 再安装：
python -m pip install --upgrade pip
python -m pip install --upgrade setuptools
问题三
随后出现下列错误：

网上提示需要安装vc++ ，参考：github.com/grpc/grpc/i…
I have downloaded and installed latest vc++ build tools from visualstudio.microsoft.com/visual-cpp-…; still facing the same issue.
但问题并没有解决，后面一直无法找到解决方法，最后只好升级milvus==2.3.3到最新的版本，可正常安装。
pip install pymilvus
