I try to run the AiiDA-core python package with the example given here.

According to the instructions here:, I can use the verdi shell command to invoke a ipython shell which can do the completions correctly.

But when I edit the above mentioned script with wing, then the corresponding completions will be disabled. Say for the following code snippets:

from aiida import load_profile

from aiida.engine import submit
from aiida.orm import load_node, Code, Dict

code = Code.get_from_string("wannier90-3.1.0-wannier-manual")  # REPLACE <CODE LABEL>
# Prepare the builder to launch the calculation
builder = code.get_builder()

All of the builder.* part will not have completion suggestions. On the other hand, if I put the cursor at the end of the above code block and then running the code with Debug to Cursor ( Alt + F5 ). At the end, the corresponding completions will be enabled.

But how to enable the tab-completion without entering the debug mode?

Any hints for this problem?

If you're not debugging or working in the Python Shell, Wing is using only static analysis to offer completion, and the code where it's failing is created dynamically in a way that resists static analysis. You can get Wing to also use dynamic/runtime analysis by setting a breakpoint and running to it, or working interactively in the Python Shell. That way it should be reporting what is actually there at runtime, as does any shell like iPython.
