问题
I am trying to install TensorFlow with GPU support on Windows 10, but I get an error (shown below) when importing it. The CPU version works fine.
I have
- installed
tensorflow-gputhrough pip - updated the NVidia drivers for my GTX 1050 with GeForce Experience
- installed CUDA 10.1 with NVidia's network installer
- installed cuDNN 7.5.0.56, taking care of copying every file in the right CUDA folder
- installed TensorRT 5.1.2.2 via the zip method and copied the relevant DLLs in CUDA again
This is the error:

回答1:
The problem was that I installed CUDA 10.1 instead of 10.0. TensorFlow isn't yet compatible with 10.1.
回答2:
Yes, some versions of TensorFlow doesn't support CUDA 10.1, in that case, CUDA 10.0 or lower version will solve your issue.
回答3:
This is how i resolved it, If you are using pip or pip3 you have less chance succeeding in first time.
- Uninstall Python,CUDA, CuNN, Tensorflow-gpu (if you already installed)
- Install ANACONDA or MINICONDA
- Open ANACONDA prompt and run following command:
conda create --name tf_gpu tensorflow-gpu
- This will create an environment tf_gpu whcih will install all compatible versions of Python, CUDA, CuNN and Tensorflow
- once all the packages installed open the ANACONDA prompt and type the following command
conda activate tf_gpu
- This will change the conda '(base)' to '(tf_gpu)' environment
- Then type python as usual to activate the python prompt
- If you want to deactivate the 'tf_gpu' environment
conda deactivate
