Error while using Tlt-infer

Accelerated Computing Intelligent Video Analytics Transfer Learning Toolkit
#1

Hi everyone, I’m training a Detectnet_v2 model on Tlt and apparently everything went fine until the inference command it shows this

My goal is to train a model to use in Isaac SDK so I’m following its tutorial
I can’t put my spec file as a new user but I checked it many times and it looks fine because I only used the default config unless this error means there is something wrong with it
I don’t know what to do can anyone help me please

Could you please paste your detectnet_v2_inference_kitti_tlt.txt here?

Sure

Thank you

In your config file, I can see there are 11 classes.
But actually how many classes did you train?

Also, in default config file inside the docker, there is an issue for car/cyclist/pedestrian. The key does not match output_map.

key:“car”
value: {
confidence_model: “aggregate_cov”
output_map: “person”

should be

key:“car”
value: {
confidence_model: “aggregate_cov”
output_map: “car”

Please modify the three classes.

I changed the output_map but the error persist, I trained 11 classes, although some of them are with 0 precision
Here is my spec file for training, for retraining it’s basically the same
