Cannot import additional modules from the main plugin file about tuiview-plugins HOT 3 CLOSED

Original comment by Sam Gillingham (Bitbucket: gillins, GitHub: gillins).

You might want to review how modules are imported and where from in Python (https://docs.python.org/3/tutorial/modules.html#the-module-search-path). You’ll also need to create an __init__.py file in the directory so Python will see it.

The plugin mechanism in Tuiview is pretty basic - it just loads the file and doesn’t make any other part of your source tree “import-able”. You need to do this yourself. I would recommend creating a Python package (https://packaging.python.org/tutorials/packaging-projects/) called foo or whatever with your plugin support code and install it (either in the default location or on your $PYTHONPATH). Then in your plugin import that module and call what you need.

I should have explained myself properly. My directory structure is as follows:

‌

|-- tuiview_plugins/demo_plugin
    |-- __init__.py
    |-- demo_plugin.py
    |-- foo
    |   |-- __init__.py
    |   |-- bar.py

I do have a __init__.py inside foo. From the demo_plugin.py, I am using from <dot_delimited_path_from_cwd>.foo.bar import * to import the module, where cwd signifies current working directory. I also tried changing the working directory to tuiview_plugins/demo_plugin first and then import using foo.bar import *. Both the approaches did not work. However, both approaches work when simulating the same situation in python console.

Since the recommended approach is to package and install the additional modules I will try that.

I have another query if you don’t mind, if I want my plugin to have GUI (something like dialog box / wizard etc.) what is the correct / recommended way to implement that? I am trying to develop a plugin to classify temporal image stack and visualize in tuiview.

I suspect you need to add the path to tuiview_plugins/demo_plugin/foo to your $PYTHONPATH

It’s probably working in the console because it is looking relative to your current directory. From inside TuiView, it will be looking relative to where TuiView is installed which isn’t much help to you. But yes package is probably easiest.

I don’t have any particular advice about developing GUIs. You will need to use PyQt5 to be compatible with TuiView and there are plenty of examples online (http://zetcode.com/gui/pyqt5/ is a good start). Of course there is plenty of code in TuiView itself you may be able to use as a guide.

Good luck!
