Phishing classifier: MaybeStartImageEmbedding failure

[V. A.]

I'm working on a project on the phishing classifier and debugging I'm facing this issue:

the if:

if (!image_embedder_->is_ready()) 

inside MaybeStartImageEmbedding blocks the image embedding;

backtracking this means that:

bool PhishingImageEmbedder::is_ready() const {
  return !!ScorerStorage::GetInstance()->GetScorer();
} 

returns always a nullpointer 

I tried using Google API keys and the buildflag build_with_tflite_lib = true but nothing changes

is there something missing?

I get an error about gpu but it shouldnt be a problem
