"Now we'll build Data, but as an LLM Agent that can use tools outside of the LLM. In addition to using RAG to access \"long term memory\" of everything Data ever said in tha past, we'll give him a couple of additional capabilities: performing numeric calculations (which LLM's tend to struggle with on their own,) and access current information via a web search.\n",
"\n",
"We will start by parsing the original scripts and extracting lines spoken by Data. As before, you will need to upload all of the script files into a tng folder within your sample_data folder in your CoLab workspace first.\n",
"\n",
"An archive can be found at https://www.st-minutiae.com/resources/scripts/ (look for \"All TNG Epsiodes\"), but you could easily adapt this to read scripts from your favorite character from your favorite TV show or movie instead.\n",
"\n",
"We've done all of this before, so I'm combining all of the code to load up Data's past lines into a vector store together below. We'll pick up again as we incorporate this into an agent. If you need an explanation of how we are populating this vector store, refer to the earlier RAG exercises in the course.\n",
"\n",
"Also be sure to provide your own OpenAI secret key. Click on the little key icon in CoLab and add a \"secret\" for OPENAI_API_KEY that points to your secret key."
