(SOLVED) Failed to install Tensorflow.js for CPU

[JetSetDoritos]

Recognize was working fine, until earlier it started asking to download the machine learning models. When I run the occ command for the models it hangs indefinitely.

I'm on Recognize 4.3 and Nextcloud 27.0. Running on x86_64, 16GB RAM, Ubuntu 23.04

In the logs Recognize just repeats

RuntimeException: Classifier process timeout

and

Classifier process output: 2023-08-01 07:45:02.565015: I tensorflow/core/util/util.cc:169] oneDNN custom operations are on. You may see slightly different numerical results due to floating-point round-off errors from different computation orders. To turn them off, set the environment variable TF_ENABLE_ONEDNN_OPTS=0. 2023-08-01 07:45:02.597691: I tensorflow/core/platform/cpu_feature_guard.cc:193] This TensorFlow binary is optimized with oneAPI Deep Neural Network Library (oneDNN) to use the following CPU instructions in performance-critical operations: AVX2 AVX_VNNI FMA To enable them in other operations, rebuild TensorFlow with the appropriate compiler flags.

When I try and reinstall Recognize from the Nextcloud Apps page it installs but this shows in the logs.

I think an apt-get upgrade that day may have broken the environment somehow?

Building from source got it working again
