I followed the installation steps in the win branch (pip install pyautogen), then modified and renamed OAI_CONFIG_LIST_sample.json as suggested, and ran the new test (python test/twoagent.py). The first agent turn replied with code as expected. I pressed enter to use auto-reply, and got the error mentioned in issue #17 :

pywintypes.error: (2, 'CreateFile', 'The system cannot find the file specified.')

Then I did pip install docker and ran the test again. The error changed:

docker.errors.DockerException: Error while fetching server API version: (2, 'CreateFile', 'The system cannot find the file specified.')

Could you use pip install -e. instead of pip install pyautogen?

This worked, and after enough turns (test1.txt) it displayed the chart:
