python import - VnPy - ImportError: No module named
Dec 07, 2018 · 1 Answer1. Show activity on this post. The vnctpmd module, is the API interface for CTP broker of the VnPy package. As for every other API interface, you need to first build it, and then import it. In your case, you probably didn't build the CTP interface when prompted during the installation of VnPy, so now run.py can't import the module.
