error while using other embedding models

[thedonalddon]

When I use other embedding models instead of nomic-embeded-text, I meet this error:

❌ Errors occurred during the pipeline run, see logs for more details.

Then I found the problem was in graphrag\llm\openai\openai_embeddings_llm.py:

for inp in input:
            embedding = ollama.embeddings(model="nomic-embeded-text", prompt=inp)
            embedding_list.append(embedding["embedding"])

The model name "nomic-embed-text" is hardcoded in the class.
