Error with Python face_recognition

Autonomous Machines Jetson & Embedded Systems Jetson Nano
1

Install face_recognition:
sudo pip3 install face_recognition

Download demo:
git clone --single-branch GitHub - ageitgey/face_recognition: The world's simplest facial recognition api for Python and the command line

run demo:

cd examples
python3 facerec_from_webcam_faster.py

When a face is detected, the array has an item and the error occurs.

/usr/local/lib/python3.6/dist-packages/face_recognition/api.py:222: RuntimeWarning: invalid value encountered in less_equal
return list(face_distance[known_face_encodings, face_encoding_to_check) <= tolerance)

Hi,

There is an cuDNN error on the Jetson Nano which leads to some issue in the dlib.
You can find more information in this topic:
[url]https://devtalk.nvidia.com/default/topic/1049660/issues-with-dlib-library/[/url]

In summary, you will need to build dlib from source with the steps shared in this comment:

Thanks.

We have confirmed that this issue is fixed in the cuDNN v7.6.1.

how can I update to cuDNN v7.6.1.?

Hi,
I had the same error on the Jetson Nano with face recognition:
/usr/local/lib/python3.6/dist-packages/face_recognition/api.py:222: RuntimeWarning: invalid value encountered in less_equal
return list(face_distance[known_face_encodings, face_encoding_to_check) <= tolerance)

And I go to the download page, there isn’t cuDNN v7.6.1
https://developer.nvidia.com/rdp/cudnn-download

Please help, thanks.

Hi,

cuDNN 7.6 is not available yet.
Please wait for our future JetPack release to get the fix.

Currently, you can apply the workaround mentioned here first:

Hi,

I had the same error on the Jetson Nano with face recognition.
But, I have confirmed that face recognition works well on Windows and Raspberry Pi 3 B (with Python3).

Hi nanos,
