[NodeJS] Error to predict using text features #2523
Description
I'm trying to use my model from NodeJS, via the catboost NPM package, but can't figure out a way to provide the text features to the predict method. Can someone please help?
import { Model } from "catboost"
const myModel = new Model('./mymodel.bin')
const prediction = myModel.predict([[-358.48]], [['Some Description', 'false']])
The predict call errors like this:
Error: NCB::NModelEvaluation::NDetail::TCpuEvaluator::Calc(TArrayRef<TArrayRef<float const> const>, TArrayRef<TArrayRef<TBasicStringBuf<char, std::__y1::char_traits<char> > const> const>, unsigned long, unsigned long, TArrayRef<double>, NCB::NModelEvaluation::TFeatureLayout const*) const+430 (0x11E88547E)

FWIW, my model was trained with the following column definition:
0 Text description
1 Label category
2 Num amount
3 Categ isEnabled
And catboost dependency is locked like this:
"node_modules/catboost": {
"version": "1.25.1",
"resolved": "https://registry.npmjs.org/catboost/-/catboost-1.25.1.tgz",
"integrity": "sha512-Qf0jLkBYIHfHjczkgSk+fZrSszu+foChVPwfhcj+Out6RDqOdorjh5cvv660wM2trr9++4ajwdR8PzfjP8vl1A==",
"hasInstallScript": true,
"dependencies": {
"node-addon-api": "^1.1.0"
}
}
Finally, the model was generated using the catboost CLI for arm64:
$ catboost --version
