Installing cuda toolkit on rtx 2070 q max

I have downloaded and installed cuda toolkit when I run nvcc -V on my cmd it shows the installed version of cuda library ive also added path of cudnn in variable environment but the issue is when I import tensorflow to do my work in pycharm or cmd it shows the following error :

2020-10-04 03:39:02.465905: W tensorflow/stream_executor/platform/default/] Could not load dynamic library ‘cudart64_101.dll’; dlerror: cudart64_101.dll not found
2020-10-04 03:39:02.471847: I tensorflow/stream_executor/cuda/] Ignore above cudart dlerror if you do not have a GPU set up on your machine.’
it hurts when it says you don’t have GPU setup on your machine .
please help!!
thanks in advance
