Tensorflow 2.5 with GPU device (Python 3.9, Cuda 11.2.2 , Cudnn 8.1.1) Conda environment - Windows 10

I want to share the procedure to work with your GPU with the new stable version of tensorflow 2.5 in case someone is having problems with the update.

I have noticed an improvement in training time.

According to official information


  1. Install Anaconda with Python 3.9
    source: https://docs.conda.io/en/latest/miniconda.html

  2. Install the latest version of your GPU driver.

  3. Install Cuda Toolkit 11.2.2
    source: https://developer.nvidia.com/cuda-toolkit-archive

  4. Download Cudnn 8.1.1
    source: https://developer.nvidia.com/rdp/cudnn-archive

Now just copy the files inside from each Cudnn folder and paste into your Cuda folder, follow this example.
source: https://docs.nvidia.com/deeplearning/cudnn/install-guide/index.html#install-windows

A. Copy \cuda\bin\cudnn*.dll to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.2\bin.
B. Copy \cuda\include\cudnn*.h to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.2\include.
C. Copy \cuda\lib\x64\cudnn*.lib to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.2\lib\x64.

  1. Go to your environment variables, Under “System Variables” click on “New” and create the CUDA PATH

  2. Create a new conda environment

conda create --name TF-2.5 python=3.9
conda activate TF-2.5

  1. install tensorflow and libraries

pip install tensorflow
pip install tensorflow-datasets
pip install tensorflow-hub
pip install jupyter
pip install numpy
pip install matplotlib
pip install pandas

if you need to use jupyter notebook with the new version of python and tensorflow (very important)

conda install -c conda-forge ipykernel

  1. Register your environment

python -m ipykernel install --user --name TF-2.5 --display-name “Python 3.9 (Tensorflow 2.5)”

  1. Testing your environment

jupyter notebook


that’s all works completely fine for me.




Thanks for sharing, Ricardo. Just to confirm, is this Windows 10 21H1 or another version of Windows?


Hi Yarri, Your welcome! yes it’s that version.

Hi, Ricardo.
from what folder conda should be run ?
When I run it from the default folder of cmd, error happens:

C:\WINDOWS\system32>conda create --name TF-2.5 python=3.9
‘conda’ is not recognized as an internal or external command,
operable program or batch file.
Thanks in advance.

Hi Sasha, Because you have to create the environment from the Anaconda Prompt (miniconda3) not from cmd.

I could not find it in the folders seemed relevant:
C:\Users\User\miniconda3 ;

Thanks a lot, Ricardo. Now it works perfectly!



I cant use my GPU with tensorflow 2.4.0!
I have CUDA 11.0 with 8.0.4 compatible for cuda 11,
all works in python with interpreter (Conda python 3.7.6 with virtual env)

When process image it’s too slow! The GPU isn’t used… why??? What’s wrong? I lost 4 days to find the error… but all .DLL are loaded successfully, i can’t see any error

I show you my screenshot…

This procedure works good with Tensorflow 2.6 just keep following the instructions.
