Tensorflow 2.3.0 does not detect GPU

Question

The tensorflow does not detect the GPU card. I have following the procedures suggest at Nvidia website and tensorflow/install/gpu.

How can I fix it?

I am using the following packages and drives:

NVIDIA

tensorflow-estimator      2.3.0                    pypi_0    pypi

I use the following code to check it;

IPython 7.17.0 -- An enhanced Interactive Python.

from tensorflow.python.client import device_lib
device_lib.list_local_devices()

Result

Answer 1

Check the software requirements:Here

It says cudnn version = 7.6

Make sure you have installed all the c++ redistributables - Here

Make sure you have the appropriate python version. - Here

Finally, make sure you have set the path to Cuda and cudnn in your system.

Make sure the installed NVIDIA software packages match the versions listed above. In particular, TensorFlow will not load without the cuDNN64_7.dll file. To use a different version, see the Windows build from source guide.

This is stated in TensorFlow documentation which seems to be your issue
