Drawing fails on Google Colab about pyganja

[hugohadfield]

@timcash I have just triggered a release so the version in pypi should now be equal with master https://pypi.org/project/pyganja/0.0.13/

Ah yes, this was fixed in this commit but looks like we haven't done a release in a while. We will do one very shortly, in the meantime install from master will be a work around for this bug, try changing that line to:

!pip install git+https://github.com/pygae/pyganja.git

On google collab however I am still not getting any output although there is no error, I've started looking into that but I suspect it may be to do with outputting javascript into collab which, like jupyter lab, it probably won't like

Changing the test to:

!pip install git+https://github.com/pygae/pyganja.git
!pip install clifford

from clifford.tools.g3c import random_line, layout
from pyganja import *

gs = GanjaScene()
js = generate_notebook_js(gs, sig=layout.sig)
print(js)

import IPython
display(js)

print('Cell complete')

reproduces the javascript error failure to draw. The cell executes and prints cell complete with no error messages but also no output. In the development console however we get the following error:

Adding the line:

display(IPython.core.display.HTML('''<script src="/static/components/requirejs/require.js"></script>'''))

gets rid of the requirejs error but still no output visible in colab

Wonderful

I am facing the same problem: installed node.js and pyganja v0.015 on mac. Clifford working well.
UserWarning: Failed to import cef_gui, cef functions will be unavailable from .script_api import *

running the code below:

from clifford.tools.g3c import *
from pyganja import *

object_array = [
random_conformal_point(),
random_point_pair(),
random_circle(),
random_line(),
random_sphere(),
random_plane()
]

The simplest way to use pyganja

draw(object_array,
static=False ,
scale=0.1)
