how to convert list of lists into matrix

With PyCall I can just do a Matrix(data) , but with PythonCall there doesn't seem to be a method available for converting a python list of lists into a matrix.

Good question!

One way would be something like pyconvert(Matrix, numpy.array(data)).

Or pyconvert(Vector{<:Vector}, data) gets you a vector of vectors that you can hcat together.
