How to solve the problem?
It seems you are trying to use the TensorFlow-GPU version and you have downloaded conflicting software versions for it.
Note: GPU support is available for Ubuntu and Windows with CUDA enabled cards only.
If you have a Cuda enabled card follow the instructions provided below.
As stated in Tensorflow documentation. The software requirements are as follows.
Nvidia gpu drivers - 418.x or higher
Cuda - 10.1 (TensorFlow >= 2.1.0)
cuDNN - 7.6
Make sure you have these exact versions of the software mentioned above. See this
Also, check the system requirements here.
For downloading the software mentioned above see here.
For downloading TensorFlow follow the instructions provided here to correctly install the necessary packages.

I am using a package that requires tensorflow-gpu == 2.0.0 and CUDA=10.0.0 with cudann==7.6.0
I am running this code on a NVIDIA gpu cluster and when I run nvidia-smi it shows
this. It still shows cuda 11, which I guess is the one installed on the actually server.
I was told that I can basically 'override' this version by installing the cudatoolkit in the version that I need. I did that and installed cudatoolkit==10.0.
Unfortunately I am now running into a problem when trying to run an LSTM based model with tensorflow-gpu. I get the following:

In the path I still see cuda11. Is this causing the problem? How can I resolve this?
As you mentioned in the comment you need to use TensorFlow 2.1, then you need to install cuDNN 7.6 and CUDA 10.1 specifically.
Please follow the below tested build configurations to know about Python and TensorFlow versions compatible CUDA and cuDNN .
Please check this link for more details on GPU setup.
How to set up different versions of CUDA in one OS?
Here is my problem: Lastest Tensorflow with GPU support requires CUDA 11.2, whereas Pytorch works with 11.3. So what is the solution to install both libraries in Windows and Ubuntu?
One solution is to use Docker Container Environment, which would only need the Nvidia Driver to be of version XYZ.AB; in this way, you can use both PyTorch and TensorFlow versions.
A very good starting point for your problem would be this one(ML-WORKSPACE) : https://github.com/ml-tooling/ml-workspace
I get this error when I run the model.fit_generator code to train images using the CNN model. I don't understand the error, and what should I do? Can anyone help me?
this is the full error description
`Loaded runtime CuDNN library: 8.0.5, but the source was compiled with: 8.1.0. CuDNN library needs to have a matching major version and equal or higher minor version. If using a binary install, upgrade your CuDNN library. If building from sources, ensure the library loaded at runtime is compatible with the version specified during compile configuration.
I had the same error "tensorflow/stream_executor/cuda/cuda_dnn.cc:362] Loaded runtime CuDNN library: 8.0.5 but source was compiled with: 8.1.0."
I solved it by downgrading the TensorFlow version, here it says that you use a new version of TensorFlow that is not compatible with the google colab CuDNN version. I used TensorFlow 2.4.0 plus all the dependence required on version 2.4.0.
Here it says which version of TensorFlow to use for cudnn compatibility, https://www.tensorflow.org/install/source
You should always have version of libraries installed that is matching the version dependency you want to use is compiled with.
You can download the version you need from nvidia website or use conda for package management. It will handle all dependencies for you.
You can miniconda and type conda install -c anaconda tensorflow-gpu to get it sorted for you. If you need a specific version of python, you can create environment with it.
My solution:
After confirming that my cuda and cudnn versions are compatible with tensorflow, I first thought that the system did not synchronize after the installation was completed. After several restarts, it was found that it was not and could not be the problem, so I started to check all the cuda in the system. For the software that depends on cudnn, matlab was uninstalled during the period but it was useless. Later, I thought that pytorch is also related to cuda and cudnn. I checked the version of pytorch and found that I was using torch 1.8, and the cuda it was adapted to was 11.1 , The corresponding cudnn is 8.0.5, now the case is solved. Finally upgraded pytorch and solved it.
I have faced the same issue. It seems like if TensorFlow versions requires specific cuDNN version.
Check the link for required versions.

It helps me a lot,but I use different way to solve this problem.
I found that pytorch 1.8 is compatible with cudnn 8.1.0. So, instead of upgrade pytorch version, I overwrite the cudnn 8.0.5 dll library with cudnn 8.1.0 in directory D:\Program Files\Python37\Lib\site-packages\torch\lib. You can find this location with Everything, which is always helpful.
Machine Setting:
GPU: GeForce RTX 3060
Driver Version: 460.73.01
CUDA Driver Veresion: 11.2
Tensorflow: tensorflow-gpu 1.14.0
CUDA Runtime Version: 10.0
cudnn: 7.4.1
Note:
CUDA Runtime and cudnn version fits the guide from Tensorflow official documentation.
I've also tried for TensorFlow-gpu = 2.0, still the same problem.
Problem:
I am using Tensorflow for an objection detection task. My situation is that the program will stuck at
2021-06-05 12:16:54.099778: I tensorflow/stream_executor/platform/default/dso_loader.cc:42] Successfully opened dynamic library libcublas.so.10
for several minutes.
And then stuck at next loading process
2021-06-05 12:21:22.212818: I tensorflow/stream_executor/platform/default/dso_loader.cc:42] Successfully opened dynamic library libcudnn.so.7
for even longer time. You may check log.txt for log details.
After waiting for around 30 mins, the program will start to running and WORK WELL.
However, whenever program invoke self.session.run(...), it will load the same two library related to cuda (libcublas and libcudnn) again, which is time-wasted and annoying.
I am confused that where the problem comes from and how to resolve it. Anyone could help?
Discussion Issue on Github
===================================
Update
After #talonmies 's help, the problem was resolved by resetting the environment with correct version matching among GPU, CUDA, cudnn and tensorflow. Now it works smoothly.
Generally, if there are any incompatibility between TF, CUDA and cuDNN version you can observed this behavior.
For GeForce RTX 3060, support starts from CUDA 11.x. Once you upgrade to TF2.4 or TF2.5 your issue will be resolved.

how do you install only a CPU version of Tensorflow 2.x using pip ?
In the past, it was possible to install this 2 different versions.
Since I am running the scripts in a nonen GPU device ( without envidia card, intel card available without cuda support), I am getting following error:
2020-04-14 23:28:14.632879: W tensorflow/stream_executor/platform/default/dso_loader.cc:55] Could not load dynamic library 'libcuda.so.1'; dlerror: libcuda.so.1: cannot open shared object file: No such file or directory
2020-04-14 23:28:14.632902: E tensorflow/stream_executor/cuda/cuda_driver.cc:313] failed call to cuInit: UNKNOWN ERROR (303)
In the past my workaround was to use a CPU only version.
Thanks for the hints in advance
You can choose the CPU-only version of tensorflow depending on your python version.
Check the list here:
https://www.tensorflow.org/install/pip#package-location
e.g. you will need to do the following for Python 3.8:
pip3 install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow_cpu-2.3.0-cp38-cp38-manylinux2010_x86_64.whl
Issue solved after installing a CPU only version.
I used pin tensorflow-cpu and the version of the release. Somehow the fallback solution for CPU did not work in my setup.
