From 1e13987fba5a536965ef942f2c86549d62cef50b Mon Sep 17 00:00:00 2001 From: howlger Date: Wed, 27 Mar 2024 12:15:44 +0100 Subject: [PATCH] embedding : show full embedding for single prompt (#6342) * embedding : show full embedding for single prompt To support the use case of creating an embedding for a given prompt, the entire embedding and not just the first part needed to be printed. Also, show cosine similarity matrix only if there is more than one prompt, as the cosine similarity matrix for a single prompt is always `1.00`. * Update examples/embedding/embedding.cpp --------- Co-authored-by: Georgi Gerganov --- examples/embedding/embedding.cpp | 20 +++++++++++--------- 1 file changed, 11 insertions(+), 9 deletions(-) diff --git a/examples/embedding/embedding.cpp b/examples/embedding/embedding.cpp index 9aede7fad..536657526 100644 --- a/examples/embedding/embedding.cpp +++ b/examples/embedding/embedding.cpp @@ -178,25 +178,27 @@ int main(int argc, char ** argv) { float * out = emb + p * n_embd; batch_decode(ctx, batch, out, s, n_embd); - // print the first part of the embeddings + // print the first part of the embeddings or for a single prompt, the full embedding fprintf(stdout, "\n"); for (int j = 0; j < n_prompts; j++) { fprintf(stdout, "embedding %d: ", j); - for (int i = 0; i < std::min(16, n_embd); i++) { + for (int i = 0; i < (n_prompts > 1 ? std::min(16, n_embd) : n_embd); i++) { fprintf(stdout, "%9.6f ", emb[j * n_embd + i]); } fprintf(stdout, "\n"); } // print cosine similarity matrix - fprintf(stdout, "\n"); - printf("cosine similarity matrix:\n\n"); - for (int i = 0; i < n_prompts; i++) { - for (int j = 0; j < n_prompts; j++) { - float sim = llama_embd_similarity_cos(emb + i * n_embd, emb + j * n_embd, n_embd); - fprintf(stdout, "%6.2f ", sim); - } + if (n_prompts > 1) { fprintf(stdout, "\n"); + printf("cosine similarity matrix:\n\n"); + for (int i = 0; i < n_prompts; i++) { + for (int j = 0; j < n_prompts; j++) { + float sim = llama_embd_similarity_cos(emb + i * n_embd, emb + j * n_embd, n_embd); + fprintf(stdout, "%6.2f ", sim); + } + fprintf(stdout, "\n"); + } } // clean up
