Error to recognition

Hi,
I have this error by using your flow ...

"No descriptor file found for 7c9cec36.49682c"
but I have uploaded the image and It seems that the node don't save the description, in fact in my pc I don't find a file 7c9cec36.49682c.json

Can you help me?

PC with Ubuntu 20.04
Node-RED version: v1.2.9
Node.js version: v14.16.0
Linux 5.4.0-81-generic x64 LE

[mbrunn]

The given example outputs signal null
If I add my own images, the same "ENOENT" error appears.
@thebigpotatoe How can we help in debugging? See the logs attached.

Happy to have a look at this issue. But since the example is still working for me, I will need you to describe the exact steps that you took to do this. That way I can try replicate it here on my setup.

I am having the same issue.

"No descriptor file found for 0b73162f0f4ec079"

Here are the steps:

1. click on pencil to add new face-api...
2. Enter in name
3. Click add image button
4. add image
5. get message to click "update" to upload, There is no update button Just an "Add" button at the top.
6. Click Add, then Done, then Deploy. Error message appears.

More info from the node-red-log

When I add an image to a newdescripter I get

7 Jan 10:12:11 - [error] undefined

When I click on the "Add" button I get

Unrelated but another strange this is that on the debug messages the node ID does not display. I have never seen that before.

I resolved the majority of the issues. Your instructions state to install

npm install @tensorflow/tfjs-node
``
I installed 

npm install @tensorflow/tfjs-node@1.2.11

And then removed and reinstalled face recognition.

All of the errors are gone except for the undefined error that I state above.

One note: I have yet to get a face recognition with my testing. I will report on that when I learn more.
