Not sure where to post this problem. I encountered strange behaviour. Importing a third package can lead to the “loss” of LaTeX print of the SymPy.Sym in Jupyter. Example:

```plaintext
using SymPy
@syms x y
x*y

```

nicely prints xy in LaTeX. Then, e.g.

```julia
import Combinatorics.levicivita
x*y

```

doesn’t print it in LaTeX anymore. However, arrays of Sym are still printed in LaTeX.

```plaintext
[x*y]

```

(Julia 0.7.0, Anaconda Jupyter, Unix)

I don’t really get why and where to start to tackle this problem.

Wow, this took 12h to be fixed and released. I’m very impressed.

That’s how we roll.
