SSL error while using pip install to install tensorflow-gpu

Question

I am trying to install tensorflow-gpu by running pip install tensorflow-gpu Windows, inside an Anaconda enviornment, but I am getting the following error:

Could not install packages due to an EnvironmentError: [SSL: DECRYPTION_FAILED_OR_BAD_RECORD_MAC] decryption failed or bad record mac (_ssl.c:1977)

I also tried doing it in a command prompt with administrator access, but it still didn't work.

C:\WINDOWS\system32>pip install tensorflow-gpu

All other network-related activities(such as browsing the web) work properly on the computer. I also have the correct CUDA and cuDNN installed, along with the latest NVIDIA drivers.

I fixed this problem by purging my Anaconda installation and reinstalling it, and then installing tensorflow-gpu. However, I am still curious as to why this error even happened in the first place.

Answer 1

It's related to network connection. I faced the same error in my Ubuntu system. Hence solved it by changing my network(WiFi) connection.

Answer 2

Use the following syntax while installation packages:

pip install --user packagename
