LaTex display for mathematical equations in Synapse Analytics

Question

I am using Azure Synapse Analytics to analyse my output data using a notebook running on a Spark pool in Synapse. In the process, I have a CSV loaded (as model output) from the ADLS Gen2. One of these columns is a list of model parameters and I want to programmatically build the equation string in LaTex and print it as a part of code cell output. I tried the following way (considering it to be an example for now):

import IPython.display as disp
fr=2 
disp.display(disp.Latex("$f_r = %i$ GHz"%(fr)))

As expected, the output should be the visualisation of the LaTex string. However, I receive the following output from the code cell: <IPython.core.display.Latex object>.

I am looking for some pointers to achieve the same.

Hi @Chintan Rajvir ,

After having conversation with internal team, it is confirmed that outputting LaTeX is not directly supported in the Notebook code cell in Synapse Studio.

As of now, however, you may try with displayHTML function and to render the LaTeX expression via HTML output. This may need some HTML boilerplate like the one provided by MathJax: https://www.mathjax.org/#gettingstarted. And you may need to enable “Preview Features” on the notebook toolbar in order to properly consume external scripts in the HTML output.

An example of the HTML snippet is here: 78097-htmlsnippet.txt

And the outcome is as follows:

If you have any feedback/suggestion regarding the product improvements, I would recommend you to please share your feedback in Azure Synapse Analytics user voice forum: https://feedback.azure.com/forums/307516-azure-synapse-analytics .
