I got many probelms to install numpy package. When i execute pip commande
pip install numpy
I get the following errors

Need help please.
您可以随时下载Numpy安装程序
The error with pip shows you have a pip connection problem. I think you did not set your proxy correctly when trying to run pip install. Please check this question . You may try --proxy option for pip. Otherwise, I don't suggest any manual install for numpy.
Maybe the reason is network ,you can try once again. (it worked for me)
