Hello, @sarthakkar99! I'm here to help you with any bugs, questions, or contributions you may have. Let's work together to solve this issue.

To resolve the ImportError related to tool_call_chunk from langchain_core.messages.tool, you should ensure that you are importing the module correctly. Here is a step-by-step approach to resolve the issue:

1. Check the Import Path: Ensure that the import path is correct and that tool_call_chunk exists in langchain_core.messages.tool.

2. Use the Importer Function: The create_importer function can help transition from deprecated imports to new imports. You can use this function to dynamically import the required module.

3. Install Required Packages: Make sure that all necessary packages, including langchain-core, are installed.

Here is an example of how you might use the create_importer function to import tool_call_chunk:

from langchain._api.module_import import create_importer

# Define the module lookup for the required import
module_lookup = {
    "tool_call_chunk": "langchain_core.messages.tool"
}

# Create the importer function
importer = create_importer(__package__, module_lookup=module_lookup)

# Use the importer to get the required object
tool_call_chunk = importer("tool_call_chunk")

Ensure that you have the langchain_core package installed:

pip install langchain-core

If the module tool_call_chunk is not found, you might need to check the documentation or the source code of the langchain library to verify the correct import path ^[1].
