Tensorflow does not detect GPU altough the GPU driver and Cuda are installed

I have an Nvidia GPU (Geforce RTX 3090) and the driver is displayed in Nvidia Control Panel. I also have installed the latest version of Cuda. However, when using the following code in Python with TensorFlow:

gpus = tf.config.list_physical_devices('GPU')
if not gpus:
    print("No GPUs detected")
else:
    print("GPUs detected:")
    for gpu in gpus:
        print(gpu)

It always shows me, that no GPU is detected. Can you tell me what I have to do in order to make Tensorflow use the GPU?

EDIT: I am using PyCharm and downloaded Python directly (so I don't use something like Anaconda).

Update: Here is the nvidia-smi output from the cmd:

Update: I downgraded to tensorflow 2.10 and get some new error messages:"2023-07-15 15:15:23.440924: W tensorflow/stream_executor/platform/default/dso_loader.cc:64] Could not load dynamic library 'cudart64_110.dll'; dlerror: cudart64_110.dll not found 2023-07-15 15:15:23.441186: I tensorflow/stream_executor/cuda/cudart_stub.cc:29] Ignore above cudart dlerror if you do not have a GPU set up on your machine."

There are a few things, first of all, sometimes pycharm fails to detect installed packages. It Happens to work after restarting the pc.
Next you can check if you have the path variable for cuda setup correctly. [it should be like this][1] [1]: https://i.sstatic.net/kEVK0.png
Next if that still doesn't work, you can check the compatibility of tensorflow version with the cuda version. for reference- https://www.tensorflow.org/install/source https://www.tensorflow.org/install/source
Also check compatibility with tensorflow-gpu. if there is some problem with them, after resolving the issue, recommend restarting pycharm.
Check TensorFlow GPU Support: TensorFlow needs to be built with GPU support. You can verify this by running the following code:

import tensorflow as tf

print(tf.test.is_built_with_cuda())

these are the version i am using for tensorflow and tensorflow-gpu and my cuda version is 10.1

and whenever working on these projects, its better to be working on a venv, as different projects need different version compatibility.

According to this guide you should use CUDA ~~11.8~~ 11.2 (with CuDNN 8.1.0) for Windows and TF 2.10. You wrote that you installed "the latest version of CUDA", which is 12.2 right now. Can you verify that? To check your installed cuda version you can try to run

from tensorflow.python.platform import build_info as build
print(build.build_info['cuda_version'])

or for a comand-line one-liner:

python3 -c "from tensorflow.python.platform import build_info as build;print(build.build_info['cuda_version'])"

But given that TensorFlow can't find your GPU, I'm not sure that works. You can also look at C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA which version the subfolder name is.

The error Could not load dynamic library 'cudart64_110.dll'; dlerror: cudart64_110.dll indicates that TensorFlow looks for libraries with the version 11.

To install the right TensorFlow version, run

pip install -U "tensorflow==2.10.*"

Download CUDA ~~11.8~~ 11.2 from https://developer.nvidia.com/cuda-11-2-0-download-archive
If you want to have CuDNN, download and install it according to this guide. Be careful to choose version 8.1.0!

You can try pip install tensorflow-gpu==2.10.0 and check if it works. It should uninstall old tensorflow package and install the gpu one of version==2.10.0

I am also faced this issue. I am using anaconda. In my case problem was i installed tensorflow instead of tensorflow-gpu. so I created new env in anaconda and then installed the tensorflow-gpu. so now it using my gpu Gtx 1060

#CREATE THE ENV conda create --name ENVNAME -y

#ACTIVATE THE eNV conda activate ENVNAME

#INSTALLING CUDA DRIVERS conda install -c conda-forge cudatoolkit=11.2 cudnn=8.1.0 -y

#INSTALLING TENSORFLOW conda install tensorflow-gpu -y

conda install -c anaconda ipykernel -y

conda install ipykernel -y

#ADDING ENV TO JUPYTER LIST python3 -m ipykernel install --user --name=ENVNAME

#'VERIFY GPU SUPPORT' python3 -c "import tensorflow as tf; print(tf.config.list_physical_devices('GPU'))"
