Hello.
I needed to install the CUDA 11.3 library to fix the following error message for my RTX 3080ti
"Could not load dynamic library 'cudart64_110.dll'"
It's on the tensorflow page that you need NVidia libraries https://www.tensorflow.org/install/pip#windows-native
but this may not be obvious to those that are installing it for the first time just via pip.
Thanks.
