I am new to Tensorflow JS.

I tried to replace @tensorflow/tfjs with @tensorflow/tfjs-node after installing Python in order to speed up the training process but I got this message when running the model:

node-pre-gyp info This Node instance does not support builds for Node-API version 7 node-pre-gyp info This Node instance does not support builds for Node-API version 8 node-pre-gyp info This Node instance does not support builds for Node-API version 7 node-pre-gyp info This Node instance does not support builds for Node-API version 8 2022-07-03 21:58:49.916274: I tensorflow/core/platform/cpu_feature_guard.cc:151] This TensorFlow binary is optimized with oneAPI Deep Neural Network Library (oneDNN) to use the following CPU instructions in performance-critical operations: AVX2 To enable them in other operations, rebuild TensorFlow with the appropriate compiler flags. Orthogonal initializer is being called on a matrix with more than 2000 (4096) elements: Slowness may result.

And then the training starts in a low pace.

Do you have any suggestions in order to fix this problem?
