Import tensorflow as tf import tensorflow. One of the operations he tried was the multiplication of matrices using npdot for Numpy and tfmatmul for TensorFlow.
Import tensorflow as tf import numpy as np Build a graph graph tfGraph with graphas_default. Binary pip install tf-nightly-gpu TensorFlow version use command below. TensorFlow 140 or newer with GPU support eg.
Device_name gpu0 else. GCCCompiler version if compiling from source. The GPU 2 is done by Scikit-cuda which is a wrapper for pycuda.
Tensorflow music tensorflow mac m1 tensorflow model training tensorflow m1 chip tensorflow neural network. Matmul a b with tf. Assuming a Tesla V100 GPU and Tensor Core operations on FP16 inputs with FP32 accumulation the FLOPSB ratio is 1389 if data is loaded from the GPUs memory.
Matmul a b print Runtime is 25f time. For the later one we also see a breakdown of communication time between CPU and GPU. Get_variable fb 2 2 initializer tf.
