ModuleNotFoundError

[qqtop]

Getting this runtime error

nimpy.nim(1004)          pyImport
py_utils.nim(98)         raisePythonError
Error: unhandled exception: <class 'ModuleNotFoundError'>: No module named 'fdb' [Exception]

pip3 installed modules are not found anymore , code like pyos=pyImport("os") work fine
I still have compiled code where this works so not sure if this is a nimpy or Nim issue or something else.
System is debian with python3.6.7 and latest Nim devel

Edit
After further tests on several systems , this error seems to show itself only if there is a mixture of
python3.7.x standard libraries and python 3.6.x libraries on the system

So it seems you have the package installed into python3.6, but nimpy uses the latest (3.7). You can verify that by inspecting sys.path.

Looks like a duplicate of #46
