Hi there 👋. Looks like you are running TensorFlow.js in Node.js. To speed things up dramatically, install our node backend, which binds to TensorFlow C++, by running npm i @tensorflow/tfjs-node, or npm i @tensorflow/tfjs-node-gpu if you have CUDA. Then call require('@tensorflow/tfjs-node'); (-gpu suffix for CUDA) at the start of your program. Visit https://github.com/tensorflow/tfjs-node for more details.

From what I understand, the

RuntimeError: abort(Error: SOI not found). Build with -s ASSERTIONS=1 for more info.
    at process.abort (/var/www/html/custom_apps/recognize/node_modules/@tensorflow/tfjs-backend-wasm/dist/tf-backend-wasm.node.js:4685:9342)
    at process.emit (events.js:314:20)
    at processPromiseRejections (internal/process/promises.js:245:33)
    at processTicksAndRejections (internal/process/task_queues.js:94:32)

is due to an analyse on a non-jpeg file. Which is pretty strange because there is this part in the classify code command
https://github.com/marcelklehr/recognize/blob/ee3731726bd4717ae86f905af50b71ff70d97791/lib/Command/Classify.php#L129-L132
I got the same issue with one of my picture. Here is how ImageMagick analyse it:

Image: HHCouplesNamur.jpg
  Format: PNG (Portable Network Graphics)
  Mime type: image/png

So it seems Nextcloud can be tricked regarding the mimetype. Once I rename my file with .png extention, classify do not take it anymore

[marcelklehr]

@Whenrow Nice catch! I'll add in some check, then.
