missing files for install & module loading error at runtime

[bertrandrigaud]

I tried to install firefly_widgets from the git repo without success. It seems files are missing:
rebuilding js and css failed
missing files: ['/PATH/firefly_widgets/firefly_widgets/static/extension.js', '/PATH/firefly_widgets/firefly_widgets/static/index.js']

Then I tried to install it from the pip repo, and it worked fine (files are in the tar.gz of the pip repo)
but when I tried to run a sample code:

Any idea ?

@bertrandrigaud Thank you for trying this out and making an issue. When you installed from GitHub, did you follow all the steps for a developer installation?

The .js files in the static directory are generated by compiling the Javascript with npm. So they are excluded from GitHub in the .gitignore.

When installing via pip, did you use "pip install" or did you unpack the tarfile and use the contents? I tested "pip install" once into a conda environment, and it worked then, but perhaps the Jupyter setup steps are putting information outside the conda environments.

[bertrandrigaud]

Whoops ! I did'nt went that far in the github procedure... my fault.
But I finally installed it with pip install command. In the notebook, I can import firefly_widget, but I get this message when I run "fv" cell. In the past I managed to play with firefly_widget... What is different is that I run it on a more recent version of jupyter notebook, ipywiget, widgetnbextension... I have to mention that I'm also on a conda environment and python version is 3.6. I wonder if the key is in ipywidget new version (6.0.0) ?

[stargaser]

The version on pip was developed with ipywidgets 6.0.0. I am also running with notebook version 5.0.0 and widgetsnbextension 2.0.0, but python 3.5. I don't think the difference between python 3.5 and 3.6 will make a difference but I am checking on that.

I have seen the "Could not create model" message when something went wrong in the code. I think helpful information may be contained in the Javascript console (right-click Inspect in Chrome, right-click Inspect Element in Safari and Firefox, then select Console tab). You might see Uncaught Error: firefly has not been bootstrapped but the widgets should run in spite of that. Are there other error messages in the console?

[stargaser]

I have made a new python=3.6 conda environment and pip-installed firefly_client into it. I am able to reproduce your problem with the "Could not create model" message. I am seeing an error Failed to load resource: net::ERR_UNKNOWN_URL_SCHEME in firefly_loader.js.

Also, after the initial pip installation, the jupyter nbextension enable --py --sys-prefix firefly_widgets step failed when trying to import numpy. I had to install astropy, jupyter, ipywidgets using conda for the "jupyter nbextension enable" to run successfully.

[stargaser]

Update: the above error was caused by incorrectly typing connect('irsa.ipac.caltech.edu:80/irsaviewer') instead of connect('http://irsa.ipac.caltech.edu:80/irsaviewer') in the first cell. Now it is working for me.

[bertrandrigaud]

work in progress... Today I tried to run a simple notebook server on my machine and I ran it sucessfully with py3.5 and py3.6.
my use case is in fact a jupyterhub running on a remote vm using https. when I try to connect to :

from firefly_widgets import connect
connect('http://irsa.ipac.caltech.edu:80/irsaviewer')
It's blocked by my web browser because of "mixed content http/https". Ok fine, I have a firefly server running on another remote vm with https. But it still does'nt work...

I'm still investigating.

[bertrandrigaud]

Reinstalled from scratch using only conda install command (not pip, except firefly_widgets of course). Works like a charm! Just a comment on the sample code:
AttributeErrorTraceback (most recent call last)
in ()
----> 1 iv.x_pan

AttributeError: 'ImageViewer' object has no attribute 'x_pan'
while y_pan seems to work...

[stargaser]

Great that it works with conda installs of the other packages!

x_pan and y_pan, along with zoom, were added from a branch that was merged to master on May 31. It's not on pip yet. I'll increment the version and update the pip package.

[bertrandrigaud]

Alright! Thanks for the help ;)
Before closing the issue, to sum up:

• install all jupyter stuff using conda install/upgrade
• be careful with mixed content (https/http)
