tried to test gen ai using a number of the samples there are issues everywhere #3263

in most packages the imports do not work because the packages were moved by the provider.

i spent hours for example to get the document summarization to work and gave up. langchaing moved their libraries which totally breaks the code.
from langchain.chains import load_summarize_chain error
etc.
due to the langchain version the import is now different.

oracle cannot expect clients to build agents in ways that will break when vendors such as langchain change their libraries
