Web24 de out. de 2024 · NVES: TensorRT’s C++ API input and output tensors are in NCHW format. This didn’t seem to be the case for me. I am using a network configured as NHWC. Despite that, I did input data in NCHW format as you mentioned was a requirement. However, the output data I am copying out via TensorRT’s C++ API was in NHWC format. Web根据算子分析,Add算子的输入数据类型支持float16、float32与int32三种;支持的数据排布格式有NCHW、NC1HWC0、NHWC、ND。 注意: 若算子输入支持多种规格,算子输入的dtype与format需要一一对应、按对应顺序进行配置,列出算子支持的所有dtype与format的组合,中间以“,”分隔。
