Я только начал изучать ИИ и никогда не использовал Tensorflow, даже Linux для меня является новым.
Я ранее установил драйвер NVIDIA 430. Он поставляется с CUDA 10.1
Поскольку Tensorflow-gpu 1.14 не поддерживает CUDA 10.1, я удалил CUDA 10.1 и скачал CUDA 10.0
cuda_10.0.130_410.48_linux.run
после установки я запустил
nvcc --version

Когда я пытался использовать графический процессор в Jupyter Notebook, код все равно не работал

c = tf.matmul(a, b)

Errors may have originated from an input operation.
Input Source operations connected to node MatMul:
b (defined at <ipython-input-9-b145a02709f7>:4)
a (defined at <ipython-input-9-b145a02709f7>:3)
Но, если я запустил этот код из терминалав Python это работает. Я вижу вывод
