ImportError: cannot import name 'FigureWidget'

[mmrahn]

I just cloned the new cufflinks version 0.14.0 which is supposed to be compatible with plotly.
When trying to import cufflinks, I get the following error:

Traceback (most recent call last):

My plotly version is 3.1.1.

Hi @mmrahn -
Are you running this from a Jupyter Notebook / JupyterLab?
Can you run directly

from plotly.graph_objs import FigureWidget

?

[mmrahn]

No, I'm not using Jupyter. I'm running it from PyCharm (sometimes in an ipython console, sometimes with the regular python interpreter).

No, I can't:

from plotly.graph_objs import FigureWidget
Traceback (most recent call last):
  File "C:\Users\monar\Miniconda3\envs\clone-athion-utils\lib\site-packages\IPython\core\interactiveshell.py", line 2961, in run_code
    exec(code_obj, self.user_global_ns, self.user_ns)
  File "<ipython-input-2-26cd651ce7af>", line 1, in <module>
    from plotly.graph_objs import FigureWidget
ImportError: cannot import name 'FigureWidget'

[mmrahn]

Okay, after a bit of digging, it turns out that FigureWidget cannot be imported because I didn't have ipywidgets installed. After installing it, I can both import FigureWidget and cufflinks.

Maybe add it to the requirements in setup.py?

[mmrahn]

Same goes for ipython btw: It is needed to import cufflinks but not included in the requirements.

[santosjorge]

Thank you @timkpaine

[mmrahn]

@santosjorge I think this does not resolve the error because ipywidgets is still not added in the requirements.txt.
Minimal example:

conda create -n test python=3.6
conda activate test
pip install cufflinks~=0.14.1
ipython

import cufflinks

raises

ImportError: cannot import name 'FigureWidget'

[timkpaine]

thats a transitive dependency through plotly

[timkpaine]

meaning plotly should enforce it

[timkpaine]

import:
https://github.com/plotly/plotly.py/blob/master/plotly/basewidget.py#L10

enforced deps:
https://github.com/plotly/plotly.py/blob/master/setup.py#L279

[mmrahn]

@timkpaine Yes, but it doesn't seem to do it.

Sorry, I can't help you more because I'm not a python expert, but the example I posted would work if plotly indeed enforced it, wouldn't it?

[timkpaine]

Yep, you should raise this issue with plotly directly

[colonelchlorine]

Looks like this could be an issue up there in Plotly: plotly/plotly.py#1111

What's strange is that I can skip cufflinks altogether and craft a Plotly graph from a Pandas DataFrame, so I just don't understand why cufflinks even needs ipywidgets to operate. Can you catch and then just skip it otherwise?

Anyone used Google Colaboratory and got this working in some way?

[timkpaine]

Could, but there are reasons to not do that, namely the JavaScript paths are different between iplot and figurewidgrt. You should raise the issue with plotly

[mahmutkocak]

In colab I have the same issue!

[colonelchlorine]

@mahmutkocak With need for graphing in colab, I just switched to Altair. Mostly does the trick.

If you installed ipywidgets and still did not work, FYI, I had to restart ipython console for newly installed ipywidgets to take effect.
