load_method with only method name

[victoriapoghosian]

Running the tutorial
https://pytorch.org/executorch/stable/running-a-model-cpp-tutorial.html

I got error
error: too few arguments to function call expected at least 2, have 1 Result<Method> method = program->load_method(method_name);

I've created model with variable shape input and seems for that I don't need to allocate memory in advance. The tutorial above could be a good candidate, but I got errors.
Could anyone help or direct to where can I find good explanation about running executorch models in C++ with variable shaped inputs.

Seems like that's the link to the stable branch. Did you check out the stable branch code or main branch? The main branch doc is https://pytorch.org/executorch/main/running-a-model-cpp-tutorial.html

Thanks for the response
Seems the part I'm interested in is the same in both docs.

Hmm we provide the option out of the box to have users opt out of memory planning their inputs, but you still need to provide arenas for any internal activations that occur in your model. So I would expect you to still need to provide the allocator.
