regarding this, it's not a supported use of Ort::Float16_t, but I believe it is going through uint16_t because there are implicit conversions between Ort::Float16_t and uint16_t. casting a float between 0.0f and 1.0f to uint16_t would result in a 0. I changed to usehalf,which...
model_fp16 = float16.convert_float_to_float16(model, keep_io_types=True) onnx.save(model_fp16, "fp16_model.onnx") 由于FP32的表示范围要远大于FP16的,所以若原始模型中的权重数据范围超出了FP16的表示范围,则会直接进行截断。 使用onnxruntime进行推理对比推理时长: import time import onnxruntim...

On the other hand, FP16 does not require recalibration of the weights. In most cases, it achieves similar accuracy as FP32. To convert a given ONNX model to FP16, use theonnx_converter_commontoolbox. import onnx from onnxconverter_common.float16 import convert_float_to_float16 ...
做模型部署边缘设备的时候,我们经常会遇到特定格式的要求。但常见的onnx2tf很多时候都不能满足我们的要求。因此,记录一下我的操作过程。 1. 环境:(linux18.04) # Name Version Build Channel _libgcc_mutex 0.1 main defaults _
官方说法是,fp16 模型,cudnn_conv_use_max_workspace 设置为 1 很重要,floatanddouble就不一定 需要改的话: 代码语言:text 复制 providers = [("CUDAExecutionProvider", {"cudnn_conv_use_max_workspace": '1'})] io_binding 可以减少一些数据拷贝(有时是设备间)的耗时。
