symbol lookup error

[sirdrakeistda]

I noticed that new faces did not get recognized. Therefore I tried to start clustering with following command:

sudo -u www-data php /var/www/nextcloud/occ face:background_job

The steps 1-7 work without problem. The last step (IMageProcessing Task) returns following error:

8/8 - Executing task ImageProcessingTask (Process all images to extract faces)
        NOTE: Starting face recognition. If you experience random crashes after this point, please look FAQ at https://github.com/matiasdelellis/facerecognition/wiki/FAQ

reinstalling pdlib helped (I don't know why)

I'm having again problems with this error. Reinstalling does not help. This time its following symbol: _ZN4dlib2tt4gemmEfRNS_6tensorEfRKS1_bS4_bNS_14operation_modeE
