在 Windows 上安装 tensorflow-gpu 时出错 10: UnsatisfiableError: The following specifications were found to be incompatible to each other

Question

For installing TensorFlow-gpu on a Windows 10 machine, I followed step-by-step this very detailed post https://medium.com/analytics-vidhya/tensorflow-2-3-0-with-gpu-support-on-windows-10-f975a552ea7c but I got stuck at the step of installing the library tensorflow-gpu (I had previusly uninstalled the already existing tensorflow one). I tried to install it both with conda and pip3 command, but I always get this error

UnsatisfiableError: The following specifications were found to be incompatible with each other:

Output in format: Requested package -> Available versions

Before reaching this point, when I try to install with conda installa command i get this

(mltrade2GPU) D:\Dropbox\PROJECTS\MLTrading>conda install tensorflow-gpu

Answer 1

There is a version conflict between the tensorflow-gpu and the current CUDA version you have installed. You need CUDA 11.0 for it to work, but you got CUDA 11.8 installed.

Either install a specific CUDA version OR adapt to a specific tensorflow-gpu package version. According to the PyPI site, version 2.10.1 should be correct: pip install tensorflow-gpu==2.10.1 !
