Checked other resources

• [X] I added a very descriptive title to this issue.
• [X] I searched the LangChain documentation with the integrated search.
• [X] I used the GitHub search to find a similar question and didn't find it.
• [X] I am sure that this is a bug in LangChain rather than my code.
• [X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

from langchain_community.embeddings import HuggingFaceInstructEmbeddings

DEVICE = "cpu"

#Initialize embeddings using a pre-trained model to represent the text data.
embedddings_model = "sentence-transformers/multi-qa-distilbert-cos-v1"

embeddings = HuggingFaceInstructEmbeddings(
    model_name=embedddings_model,
    model_kwargs={"device": DEVICE}
)

The above exception was the direct cause of the following exception:
