When I am doing an uncached load of CoreML model on ANE, I received this warning in Xcode console

Type of hiddenStates in function main's I/O contains unknown strides. Using unknown strides for MIL tensor buffers with unknown shapes is not recommended in E5ML. Please use row_alignment_in_bytes property instead. Refer to https://e5-ml.apple.com/more-info/memory-layouts.html for more information.

However, the web link does not seem to be working. Where can I find more information about about this and how can I fix it?

This particular message appears to come from one of the underlying private frameworks. (You can check the metadata of the message using log stream command.)

You can safely ignore it unless you have some real problems.
