Steps to reproduce:

1.Make sure Anaconda installed in local
2.Open the file src/test/datascience/manualTestFiles/manualTestFile.py in VS Code
3.At the top of the file it will list the things that you need installed in your Python environment
4. On the first cell click Run Below
5.Interactive Window should open, show connection information, and execute cells
6.Check the "# %% Latex"

Expected behaviour

Execute cells sucessfully without errors

Actual behaviour

Sample code

# %% Latex 

%%latex 

\begin{align} 

\nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\ 

\nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\ 

\nabla \cdot \vec{\mathbf{B}} & = 0 

\end{align}
