I am trying to test that my Jupyter notebook is using the GPU or not but when I check with this code, It shows me '0' GPU's available. But, My system is i7 10th Generation and GEFORCE RTX 2060. I have downloaded cuda and NVIDIA CNN added to the system variables and in anaconda downlaoded tensorflow GPU but I don't know why its not recognizing my GPU.
'''
print("Num GPUs Available: ", len(tf.config.experimental.list_physical_devices('GPU')))
