Have to rebuild .engine every time

[daniel.gayer]

• Hardware Platform (Jetson / GPU) Jetson Orin Nano
• DeepStream Version 7.0
• JetPack Version (valid for Jetson only) 6.0
• TensorRT Version 8.6.2

Every time I try to run inferences with Deepstream I have to rebuild the engine. I get this warning “WARNING: Deserialize engine failed because file path: {my .engine path} open error.”

I already have an engine built, I don’t why it can’t open it.

Refer to this topic.Maybe some parameters in your configuration file no match the engine file.

Engine file is rebuilt on every pipeline start

• Jetson Orin Nano • DS 7.0.0 • JP 6.0.0 v2 Warning from NvDsInferContextImpl::generateBackendContext() <nvdsinfer_context_impl.cpp:2188> [UID = 1]: deserialize backend context from engine from file :/path/to/d0_avlp_544_960_f32.engine failed, try rebuild Even though the .engine file was built and saved to the path successfully. What could be the troubleshooting steps? Thanks.
