I was testing out the changes in this branch, and it looks like I can't fetch the full suite of models (after the seventh one, the npm command exits and doesn't download the remaining ones). Are you seeing anything similar? Example output below.

No, I did not see a similar issue with fetch_models.js. And based on the provided log, the amd models added have been downloaded without error. Could you check if amd's models exist in the corresponding folder? And could you also try to run the fetch again to see if the problem persist?

The new models exist, but I think the problem is that the rest of the models aren't getting downloaded for whatever reason. I'd expect to see ~40 models downloaded. So, I'm not sure if something regressed here, as I don't see this behavior on the main branch of the parent repo.

Well, not sure what changed in the previous few hours (I restarted and changed networks in the interim, so maybe something there got things unstuck)- but at the moment, running the script seems to make it past the seventh model (it's downloading number 13 as I write this). We can consider this resolved.

I jinxed it. It bailed out after the 14th model finished downloading. Trying again. 😢

Hm, there's some degree of flakiness that I'm observing. At any rate, will treat this as a separate issue. Thanks for confirming behavior on your side.

I was trying the sample locally- I did get back an inference but did see some log output indicating attempts at local file system access... is this expected?

Including the logs from about://gpu here as well. It seems like that perhaps the computation in my local testing is happening on the CPU?
