I'm having trouble using my GPU with tensorflow.
I pip installed tensorflow-gpu 2.4.1
I also installed CUDA 11.2 and cudnn 11.2, following the procedure from: https://docs.nvidia.com/deeplearning/cudnn/install-guide/index.html#installwindows , also checking that all paths are fine and the libraries are at the correct place.
However, when I run tf.config.experimental.list_physical_devices('GPU') on my Jupyter Notebook, it doesn't find my GPU.
I also run tf.test.is_built_with_cuda(), which is returning True.
So is the problem that my GPU isn't supporting the current version of CUDA or cudnn? My GPU is "NVIDIA GeForce 605"
NVIDIA GeForce 605 card based on Fermi 2.0 architecture and I can see only Ampere,Turing, Volta, Pascal, Maxwell and Kepler are supported for CUDA 11.x.
As per #talonmies, GeForce 605 card never had supported for Tensorflow.
You can refer this for NVIDIA GPU cards with CUDA architectures are supported for Tensorflow.
For GPUs with unsupported CUDA architectures to use different versions of the NVIDIA libraries, you can refer Linux build from source guide.
Finally, you can also refer tested built configurations for Windows and linux.

I have two Windows 11 laptops with NVIDIA GeForce RTX 3060 GPUs, which I want to run Tensorflow on.
If that matters, both laptops are Lenovo Legion 5 laptops with "GPU Working Mode" set to "Hybrid-Auto Mode".
The first laptop has the following setup:
Python 3.10.7
Tensorflow 2.9.1
CUDA 11.2.0
cuDNN 8.1.1
CPU AMD Ryzen 7 6800H
GPU0 NVIDIA GeForce RTX 3060
GPU1 AMD Radeon Graphics
The second laptop has the following setup:
Python 3.10.9 Virtual Environment
Tensorflow 2.11.0
CUDA 11.2.2
cuDNN 8.1.1
CPU Intel Core i7 12th Gen 12700H
GPU0 Intel Iris Xe
GPU1 NVIDIA GeForce RTX 3060
CUDA and cuDNN were installed as per this video: https://www.youtube.com/watch?v=hHWkvEcDBO0 (except for the conda part).
On the first laptop, everything works fine. But on the second, when executing tf.config.list_physical_devices('GPU'), I get an empty list.
I have tried to set the CUDA_VISIBLE_DEVICES variable to "0" as some people mentioned on other posts, but it didn't work.
I also tried the same as the second laptop on a third one, and got the same problem.
What could be the problem?
Actually the problem is that you are using Windows, TensorFlow 2.11 and newer versions do not have anymore native support for GPUs on Windows, see from the TensorFlow website:
Caution: TensorFlow 2.10 was the last TensorFlow release that supported GPU on native-Windows. Starting with TensorFlow 2.11, you will need to install TensorFlow in WSL2, or install tensorflow-cpu and, optionally, try the TensorFlow-DirectML-Plugin
From TensorFlow 2.11 onwards, the only way to get GPU support on Windows is to use WSL2.
Tensorflow on gpu new to me, first naive question is, am I correct in assuming that I can use a gpu (nv gtx 1660ti) to run tensorflow ml operations, while it simultaneously runs my monitor? Only have one gpu card in my pc, assume it can do both at the same time or do I require a dedicated gpu for tensorflow only, that is not connected to any monitor?
All on ubuntu 21.10, have set up nvidia-toolkit, cudnn, tensorflow, tensorflow-gpu in a conda env, all appears to work fine: 1 gpu visible, built with cudnn 11.6.r11.6, tf version 2.8.0, python version 3.7.10 all in conda env running on a jupyter notebook. All seems to run fine until I attempt to train a model and then I get this error message:
2022-03-19 04:42:48.005029: I tensorflow/stream_executor/cuda/cuda_dnn.cc:368] Loaded cuDNN version 8302
and then the kernel just locks up and crashes. BTW the code worked prior to installing gpu, when it simply used cpu. Is this simply a version mismatch somewhere between python, tensorflow, tensorflow-gpu, cudnn versions or something more sinister? Thx. J.

Yes, you can check with nvidia-smi on ubuntu to see how much free memory you have or which processes are using GPU.
Only have one GPU card in my pc, assume it can do both at the same?
time
Yes, It can. Most people do the same, a training process on GPU is just similar to running a game, (but more memory hungry)
About the problem:
install based on this version table.
check your driver version with nvidia-smi But, for true Cuda version check this nvcc -V ( the Cuda version in nvidia-smi is actually max supported Cuda version. )
just install pip install tensorflow-gpu this will also install keras for you.
check if tensorflow has access to GPU as follow:
import tensorflow as tf
tf.test.is_gpu_available() #should return True
print("Num GPUs Available: ", len(tf.config.list_physical_devices('GPU')))
install based on this version table.
That was the key for me. Had the same issue , CPU worked fine, GPU would dump out during model fit with an exit code but no error. The matrix will show you that tensorflow 2.5 - 2.8 work with CUDA 11.2 and cudnn 8.1 , the 'latest' versions are 11.5 and 8.4 as of 05/2022. I rolled back both versions and everything is working fine.

I believe the problem is that CUDA 11.2 is not available for Windows 11.
Question
Tensorflow 2.4.1 doesn't recognize my GPU, even though I followed the official instructions from Tensorflow as well as the ones from NVIDIA for CUDA and NVIDIA for cuDNN to install it in my computer. I also installed it in conda (which I'm not sure if it is needed?).
When I try the official way to check if TF is using GPUs, I get 0:
import tensorflow as tf
print("Num GPUs Available: ", len(tf.config.list_physical_devices('GPU')))
Num GPUs Available: 0
Specifications
Hardware:
My NVIDIA fulfills the requirements specified by Tensorflow.
Software
I installed CUDA (with CUPTI) and cuDNN as mentioned above, so I got:
ubuntu 20.04 LTS
NVIDIA driver = 460.39
CUDA (+CUPTI) = 11.2
cuDNN = 8.1.1
In a conda environment I have:
python = 3.8
tensorflow = 2.4.1 (which I understand is the new way of having the GPU support)
and I installed extra the cudatoolkit==11.0 and cudnn==8.0 for conda as mentioned here.
Procedure followed:
It did not work when I didn't have the conda extra packages, and it still doesn't work even though I installed those extra packages.
After quite a bit of extensive research, it finally works on my computer: the latest versions of the components (i.e. CUDA 11.2, cuDNN 8.1.0) are not tested and not ensure a working result in TF 2.4.1. Therefore, this is my final configuration:
nvidia-drivers-460.39 have CUDA 11.2 drivers. However, you can still install CUDA 11.0 runtime and get it from the official NVIDIA archive for CUDA. Following the installing instructions is still mandatory (i.e. adding the path variables and so on).
cuDNN library needs to be on the version 8.0.4. You can get it also from the official NVIDIA archive for cuDNN
After installing both components on these specific versions, I successfully get:
import tensorflow as tf
print("Num GPUs Available: ", len(tf.config.list_physical_devices('GPU')))
Num GPUs Available: 1
with a few debut messages indicating that the GPU libraries were correctly imported.
EDIT:
By the way! For the folks out there who use Pycharm, either you include the environment variables also in PyCharm, or make them system-wide. Otherwise you won't still get your TF to get the GPUs.
I'm kind of new to machine/deep learning. I installed TensorFlow versions 2.4.1, I have CUDA version 11.2 but and cudNN when I want to get a list of available GPUs it returns nothing.(my GPU is 1050 ti 4GB)
I tried to install tensorflow-gpu but nothing changed.
what should I do?
Windows10-pro, single RTX 2080 Ti. I am new to Tensorflow.
I just installed tensorflow-gpu, version 2.1.0, python 3.7.7. Cuda compilation tools, release 10.1, V10.1.105. Nothing self-compiled. And I have not installed cuDNN, nor have I registered. All installation is standard, nothing self-compiled.
The tensorflow.org documentation states that cuDNN is needed to use the GPU. But my tests for GPU-usage seem to pass. For example,
tf.config.experimental.list_physical_devices('GPU') returns [PhysicalDevice(name='/physical_device:GPU:0', device_type='GPU')].
It may appear that I should just install cuDNN and not lose any more sleep. But I would still want to know if I were using the GPU so I would prefer a test that is capable of failing.
Is there a true test to see if an installation will use the GPU?
In NVIDIA GPU computing toolkit, one can verify the cuDNN installation,
On windows system,
Go to
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\include\
open cudnn.h
To utilize the Tensorflow-GPU successfully, CUDA and cuDNN are required.
Some of the Tensorflow library such as tf.keras.layers.GRU(Keras GRU layers) employs the capability of cuDNN.
Check these examples provided in Tensorflow site for GPU utilization.
