Hi,
I use the following command to install pytorch:
conda install pytorch torchvision cudatoolkit=10.0 -c pytorch
then I use the command conda list  to list the packages that have been installed with pytorch, I found the cudatoolkit but I did not found the cudnn, why? the pytorch do not need the cudnn ?
when I install tensorflow gpu version using the conda install command , the cudnn and cudatoolkit are both installed. Why pytorch only need cudatoolkit?
