开发验证
执行以下命令进行验证。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | python3 - <<'PY' import tensorflow as tf print("tensorflow_version=" + tf.__version__) print("physical_gpus=" + repr(tf.config.list_physical_devices("GPU"))) print("built_with_cuda=" + str(tf.test.is_built_with_cuda())) assert tf.config.list_physical_devices("GPU") assert tf.test.is_built_with_cuda() with tf.device("/GPU:0"): a = tf.constant([[1.0, 2.0], [3.0, 4.0]]) b = tf.constant([[1.0, 2.0], [3.0, 4.0]]) c = tf.matmul(a, b) print("tensorflow_gpu_matmul=" + str(c.numpy().tolist())) PY |
预期输出如下信息:
1 2 3 | physical_gpus=[PhysicalDevice(name='/physical_device:GPU:0', device_type='GPU')] built_with_cuda=True tensorflow_gpu_matmul=[[7.0, 10.0], [15.0, 22.0]] |
