Running Tutorial(jupyter notebook) gives NameError

[tcluri]

This is an issue in setup of LightOSM.jl by following the tutorial jupyter notebook.

Steps I followed:

1. Created a python virtual environment in my project directory.
2. Pip installed pydeck using the forked version of deck.gl in the python virtual environment
3. Created a Julia environment at the project level and installed PyCall.jl
4. Set the PyCall build to the virtual environment python version(see screenshot)

After doing these, whenever it runs the pydeck part of building the layer and defining the tooltip I get the following.

PyError ($(Expr(:escape, :(ccall(#= /home/tcluri/.julia/packages/PyCall/7a7w0/src/pyfncall.jl:43 =# @pysym(:PyObject_Call), PyPtr, (PyPtr, PyPtr, PyPtr), o, pyargsptr, kw))))) <class 'NameError'>

My understanding is that the PyCall.jl is taking the ubuntu system python(libdynload) and thus not able to import the numpy array since it is not installed on a system level but present at the python virtual environment level.

How do I fix it so it runs? What can be alternative methods(if any) like maybe using Conda.jl I can try, that will run the tutorial code?
