Run INT8 without any calibration file

Accelerated Computing Intelligent Video Analytics DeepStream SDK

Hi,
Is there any way to run the DeepStream application using INT8 engines and without its calibration files.

**• Hardware Platform (Jetson / GPU)**T4
• DeepStream Version5.0
• JetPack Version (valid for Jetson only)
• TensorRT Version7.0.0.11
**• NVIDIA GPU Driver Version (valid for GPU only)**450
• Sample application and the configuration file content
• Reproduce steps
• Reproducing rate and duration

Can you explain more about this, have you seen this feature implemented in other platform?

Hi @bcao,
I have seen it when using trtexec of tensorrt. Can the same be done for DeepStream.

No, we must provide calibration file for int8 mode
