这里展示了一个最普通的从Int8到half类型的数据转换,就直接用static_cast,可以看到它对应的PTX指令调用了一个convert.round,但实际上用convert指令它的latency是比较高的,并且可能会引起MIO Throttle。 这张slides展示了FP16的IEEE 754标准,一个16bit的数里面包含1个符号位,5个基码位,10个尾数。 假设我们有一个u...
2.获取ImageNet 训练数据 实例的Python脚本,在tensorrt/tftrt/examples/image-classification目录下,它支持TFRecord的格式类型。 当然你也可以使用给自己的一些数据类型。 3.一般的训练 pythonimage_classification.py--modelresnet_v1_50\--data_dir/data/imagenet/train-val-tfrecord\--use_trt\--precisionfp16 ...
It includes a deep learning inference optimizer and runtime that delivers low latency and high throughput for deep learning inference applications. TensorRT based applications are 40 times faster than CPU-only based platforms during inference. With this, we can optimize performance Neural Network models...
