This commit addresses the issue where input_shapes could be empty when first loading a model, which would cause model caching to be skipped incorrectly. Key changes: - Fixed incorrect iteration using session_input_names.size() as index into input_tensor vector. Now directly iterates over input_tensor. - Changed loop to include all dimensions (starting from j=0 instead of j=1), as skipping dimension 0 could result in empty shapes for low-rank tensors. - Added validation to check for null shapes and zero dimension sizes before processing. - Added check for has_dim_value() to handle symbolic/dynamic dimensions properly, only including dimensions with concrete positive values. This ensures model caching works correctly when valid input shapes are available.
This reverts commit 60c8226.
…ted shapes. let MIGraphX treat this as a static shape

There was a problem hiding this comment.
Microsoft has stopped accepting PRs that add to or remove from this structure (in general, all changes modifying any Provider API). They want us to use ProviderOptions instead. The reason is that with the new Auto EP interface, any change here will break backward compatibility.
