I used Prompt flow and LangChain to create and deploy an AI application.
I used the Prompt Flow extension to create a Chat flow
I accepted the default flow name
I clicked the Open menu item
I selected the + Create Virtual Environment... menu item
I selected the Venv option
I selected the Python version 3.12.4
I selected the generated requirements.txt file
I (briefly) selected the Global environment
I selected the .venv environment again
The "Can not find a valid python package" error was fixed
I selected an exiting connection and the gpt-3.5-turbo large language model
I tried to test the flow
An error message showed that the "promptflow-tools" package was required
I added promptflow-tools to the requirements.txt file and ran pip install.
I tested the flow asking who the Democratic Nominee for Present was. The large language model was unable to provide an up-to-date answer
I added a new node
I selected Python
I accepted the generated name
I asked for a new file
python_node_n8ln.py
I added more packages to the requirements.txt file
I set the Python node's inputs
I set the outputs's input
I removed the chat node
I tested the updated flow
The flow was able to provide an up-to-date response
The flow could have used the Duck Duck Go search "tool"
The flow could have used the Wikipedia "tool"
I selected the Build as docker menu item
I created a DOCKER folder
I clicked on the Create Dockerfile link
I navigated into the DOCKER directory and used docker build to create a docker image
I used Docker Desktop to create a container based on the new Docker image
I specified a local port 8080 and an OpenAI key
The Docker container started
I was able to access the container using port 8080
