Description

I am currently using the nvinfer plugin to perform classification for an image. Ran into a weird error regarding the input format.

model-colour-formats=0 (RGB)

0:00:04.980314545 20682     0x35f94b90 ERROR                nvinfer gstnvinfer.cpp:613:gst_nvinfer_logger:<dr> NvDsInferContext[UID 418]: Error in NvDsInferContextImpl::preparePreprocess() <nvdsinfer_context_impl.cpp:875> [UID = 418]: RGB/BGR input format specified but network input channels is not 3

Changing it to model-colour-formats=2 (GRAY)

0:00:05.401674841 21336      0x684f190 ERROR                nvinfer gstnvinfer.cpp:613:gst_nvinfer_logger:<dr> NvDsInferContext[UID 418]: Error in NvDsInferContextImpl::preparePreprocess() <nvdsinfer_context_impl.cpp:884> [UID = 418]: GRAY input format specified but network input channels is not 1.

The model input is as follows:

Layer (type)                    Output Shape         Param #     Connected to

Hi,
This looks like a Jetson issue. We recommend you to raise it to the respective platform from the below link

Thanks!
