The above is an example in the documentation.

I run it, but it doesn't work!

What should I do?

    $\begingroup$ This requires some initial download of data from Wolfram repository(approx 100 MB). Make sure you are on an active internet connection. $\endgroup$ – Subho Apr 30 '18 at 9:57
  • $\begingroup$ I have been connected, but there is no hint of download. How can I download data manually? $\endgroup$ – yonghui wang Apr 30 '18 at 10:32

    $\begingroup$ Please post code rather than screenshots: easier to copy paste (and less space storing data...) $\endgroup$ – anderstood Apr 30 '18 at 16:01

Quoting from the documentation of FacialFeatures introduced in MMA 11.3:

FacialFeatures may download resources that will be stored in your local object store at $LocalBase, and that can be listed using LocalObjects[] and removed using ResourceRemove.

I couldn't get ResourceRemove to work but you can still try the following:

First, clear the data already downloaded by locating the particular resource folder under Resources inside the directory $LocalBase$. On my PC it was 6a8. It may or may not have the same name in yours. You can try to choose your resource folder by checking the time-stamp of last modification. Now, once you have located the folder, proceed to first delete it.


Then open a new session to clear the existing cache containing the resource data.

Now, re-evaluate your code. This will force a re-download from the Wolfram servers. Just ensure that you have a stable enough internet connection this time.

  • $\begingroup$ I deleted the resource data "6a8" in the folder.It's amzing.My problem have been solved.Thank you very much! $\endgroup$ – yonghui wang Apr 30 '18 at 14:01
  • $\begingroup$ @yonghui wang Happy to help! $\endgroup$ – Subho Apr 30 '18 at 14:07
  • $\begingroup$ Same problem (v11.3.0), same ressource name ("6a8"), solved by your DeleteObject command. However it seems it did not work until I removed the first "/" in the command, i.e: DeleteObject[LocalObjects["Resources/6a8"]] ... $\endgroup$ – SquareOne May 11 '18 at 22:23
  • $\begingroup$ @SquareOne Both should be fine. I don't know why putting the first slash didn't work. $\endgroup$ – Subho May 12 '18 at 3:07
