Can't use the _ctx.onnx file created using trt_dump_ep_context_model.

[BengtGustafsson]

Describe the issue

I try to use the new Embedded engine model / EPContext model functionality for TRT provider.

The creation step succeeds and a _ctx.onnx file is created in the designated directory. This file is 762 bytes in length which seems very small.

On the second run, to utilize the purported speed improvement, I load this file into a memory buffer and provides its address and length to the ort::Session constructor instead of the original onnx blob. Then the constructor throws and unfortunately I only get a ORT_FAIL error code and no message.

I have tried setting the various trt_* option flags trt_engine_cache_enable, trt_dump_ep_context_model and the paths to the same values as before or leave them empty. I have not moved the file since cache creation. Same error every time.

I would be surprised if this depends on something with the model contents, all our models fails equally. It is probably something related to using a blob to the ort::Session constructor instead of a filename. In any event it should work or produce a real error message. I tried changing the constructor used when creating the second ort::Session to one that used the filename of the _ctx.onnx file as a full path, but got basically the same problem. The few last lines of that log appears last here.

Here is the verbose log output for the creation run and then when it fails (after some empty lines). Had to remove some hopefully uninteresting lines to make it fit 65535 chars.

Last part of output when using the ort::Session ctor with filename, specifying the _ctx.onnx file's full path:

To reproduce

Create the cache by constructing an ort::Session with:

trt_engine_cache_enable = true
trt_dump_ep_context_model = true
trt_ep_context_file_path = my_full_path_to_empty_existing_directory
trt_engine_cache_path = my_full_path_to_empty_existing_directory

and the original onnx data as a blob presented with a buffer/count.

This should generate three files in the directory, one of which is _ctx.onnx and the others something like:
TensorrtExecutionProvider_TRTKernel_graph_torch-jit-export_5359030231610903815_0_0_sm86.engine
TensorrtExecutionProvider_TRTKernel_graph_torch-jit-export_5359030231610903815_0_0_sm86.profile

I have no idea what that hash is.

Next time around just replace the contents of the blob with the contents of the _ctx.onnx file in the same directory.

Urgency

I hope we can find a work-around with the current version, it can't be entirely non-functional I hope...

[BengtGustafsson]

I solved this by using a debug build of onnxruntime, which actually showed an error message. I had used an absolute path for the trt_engine_cache_path when I also had set trt_dump_ep_context_model = true and
trt_ep_context_file_path = "the_same_absolute_path".

In this case trt_engine_cache_path MUST be relative, it is not enough that it is actually located within the subtree rooted in the directory of trt_ep_context_file_path, I guess this is to simplify the checking logic, but it would be better to use the facilities for path normalization in std::filesystem::path to actually check if the engine cache path is within the directory of the ep context file path.

Note: Not all error messages disappear in release builds, just some.
