ERROR: The use of @xenova/transformers for importing requires ESM

When working with my Node.js application, I usually start by importing the necessary modules like this:

import { AutoModel, AutoTokenizer } from '@xenova/transformers';

Afterwards, I utilize them in my code as shown below:

const tokenizer = await AutoTokenizer.from_pretrained('bert-base-uncased');

However, upon running my script, I encounter the following error message:

> node --experimental-modules lib/index.js

No storage option exists to persist the session, which may result in unexpected behavior when using auth.
        If you want to set persistSession to true, please provide a storage option or you may set persistSession to false to disable this warning.

Error [ERR_REQUIRE_ESM]: require() of ES Module /home/me/Projects/node_modules/@xenova/transformers/src/transformers.js from /home/me/Projects/lib/pinecone/utils.js not supported.
Instead change the require of transformers.js in /home/me/Projects/lib/pinecone/utils.js to a dynamic import() which is available in all CommonJS modules.

Answer №1

Greetings from the creator of Transformers.js!

The issue you are facing is not unique to transformers.js and is related to your node resolution settings in tsconfig.json. By default, all import statements get converted to require during compilation.

To resolve this, you can do the following:

TransformersApi = Function('return import("@xenova/transformers")')();
const { pipeline } = await TransformersApi;

This approach essentially postpones the import until after compilation. For more details, refer to this link.
