The error you're encountering is likely due to a change in the LangChain framework or the Google GenerativeAI module between versions. In the provided context, there is no mention of a 'generate_content' attribute in the 'google.generativeai' module.
The GoogleGenerativeAI class in LangChain uses the 'invoke' method to generate text, as shown in the example:
from langchain_google_genai import GoogleGenerativeAI
llm = GoogleGenerativeAI(model="gemini-pro")
llm.invoke("Once upon a time, a library called LangChain")If you're trying to use a 'generate_content' method, it might have been deprecated or renamed in the newer versions of LangChain or the Google GenerativeAI module. You should check the documentation or source code of these modules to verify the available methods and their usage.
If 'generate_content' was a method in an older version of LangChain or Google GenerativeAI, you might need to update your script to use the 'invoke' method instead, or any other method that replaces 'generate_content' in the newer versions.
Regarding the changes between LangChain versions 0.1.0 and 0.1.1, the AttributeError could have been caused by the relocation of the "create_spark_dataframe_agent" from the main LangChain package to the experimental package. In version 0.1.1, an ImportError is raised when trying to access this agent, indicating that it has been moved to "langchain_experimental".
To resolve this, you need to install the langchain experimental package and update your import statement from the old path to the new path. The old path is "langchain." + here + "." + name and the new path is "langchain_experimental." + here + "." + name.
Here is the relevant code snippet:
if name == "create_spark_dataframe_agent":
HERE = Path(__file__).parents[3]
here = as_import_path(Path(__file__).parent, relative_to=HERE)
old_path = "langchain." + here + "." + name
new_path = "langchain_experimental." + here + "." + name
raise ImportError(
"This agent has been moved to langchain experiment. "
"This agent relies on python REPL tool under the hood, so to use it "
"safely please sandbox the python REPL. "
"Read https://github.com/langchain-ai/langchain/blob/master/SECURITY.md "
"and https://github.com/langchain-ai/langchain/discussions/11680"
"To keep using this code as is, install langchain experimental and "
f"update your import statement from:\n `{old_path}` to `{new_path}`."
)You can find more details in the LangChain repository.
