问题 I am trying to replicate this plotly tutorial on a Jupyter Notebook with a dataset that matches the one given in the example, I just had to change the name of one column. The issue here is that being offline the command py.icreate_animations(figure) which in offline notebook mode becomes icreate_animations(figure) is not recognized. Furthermore, if I simply try the iplot(figure) command, which I use for static plots, a very long error is raised: -----------------------------------------------

Here is the code-snippet in error, it's fairly simple: notebook import matplotlib matplotlib.use("agg") import matplotlib.pyplot as plt plt.plot([1,2,3,4]) plt.show() I chose this snippet because this line alone fails as it tries to use TKinter (which is not installed on an AWS

问题 I am using the Jupyter Notebook, and am trying to create a widget, based on a template found on Github. The template uses at some point the magic %%javascript . This works fine when directly pasted in the cells of the notebook. However when I tried to make a function out of the widget, having the %%javascript expression makes it returns the error: %%javascript SyntaxError: invalid syntax Anyone knows how to "convert" the magic command so that it can be invoked properly from within a function
