It seems that images in your dataset might not have the same size, as in the VIT model https://arxiv.org/abs/2010.11929, you are using an MLP model,

if it was not the case, it is worth checking if your labels are all in the expected dimension. presumably, MMsegmentattion expects the output to be just the annotation map (a 2D array). It is recommended that you revise your dataset and prepare the annotation map.

It's difficult to give a concrete answer without looking at the full annotation file, but a KeyError exception is raised when trying to access a key that is not in a dictionary. From the error message you've posted, this key seems to be 'segmentation'.

This is not in your code snippet, but before even getting into network training, have you done any exploration/inspections using the registered datasets? Doing some basic exploration or inspections would expose any problems with your dataset so you can fix them early in your development process (as opposed to letting the trainer catch them, in which case the error messages could get long and confounding).

In any case, for your specific issue, you can take the registered training dataset and check if all annotations have the 'segmentation' field. A simple code snippet to do this below.

I'm no expert but by "every time" do you mean every time you reload the webpage? SWR wont cache the value between refreshes of the webpage for you.

Cache in this context means that two components using the same swr key ('/api/hello') will result in just one call to the api. So which ever component calls the swr first will get the api response, and the second component will get the same value from the cache.

But swr can still call the api multiple times later on to "revalidate" and send the updated response to both (or all) components that use that key.

Your First.getLayout property should be a function that accepts a page and returns that page wrapped by the HeaderLayout component.

Problem has been solved..

I just passed the url's both from ArchivedMemo (url) and the Memo(url). then i mutated those urls

Converting to string is what is causing an unexpected result. You don't need to convert .val() to string since it returns a string value:

You're right. The result of getUnitPrice() is a Promise, not a value, so what React does is it prints out the stringified version of that Promise. If you need the fulfilled value, you need a state value that will re-render the page if updated. Something like this:

Actually just for you to know:) it is possible to achieve the same thing without overloads using just conditionals even in more than one way. Just for you to note, here is one way to achieve it:

The fundamental issue is that when updating state based on existing state, you need to be sure you have the latest state information. Your getLatestAlerts function closes over the alerts constant that was in scope when it was created, so it only ever uses that version of the constant (not the updated one from a subsequent render). Your useEffect setInterval callback closes over the getLatestAlerts function that was in scope when it was created, and only ever uses that version of the function.

To be sure you have the latest state, use the callback version of the state setter instead of the constant:
