Using PCI-Express Riser USB on Raspberry Pi to use CUDA-Core Graphic Card

I would to use different Graphic Cards using a Raspberry Pi through a PCI-Express Riser on USB, in order to install TensorFlow and other libraries like Keras, scikit-learn, and much more, using the power of CUDA Cores of NVIDIA graphic cards. Is this possible?

Hello. I not think u can use CUDa with a riser like we so GPU mining.
I can be mistakedn but i try have a guy here make me a 8 GPU 4090 rig and he told me is not gonna work for ML.

Thank you. So I can use Google Coral TPU with USB interface? Maybe multiple ones?
