Hi @hkr1990,
We tried reproducing the issue, identified that input layer name is wrongly mentioned.
Its working fine now.
Please try with following command.
trtexec --workspace=4096 --onnx=mobilenetv2-7.onnx --shapes=input:32x3x224x224 --saveEngine=mobilenet_engine_int8_32.trt --int8 --explicitBatch
Thank you.
