An introduction to Gaussian processes and Julia -- we explore Gaussian processes by implementing them in Julia.
The requirements are
- Julia (https://julialang.org/downloads/). It has been tested with Julia v1.1.
- IJulia (the Julia Jupyter kernel, https://github.com/JuliaLang/IJulia.jl). To install it, run
$ julia
julia> Pkg.add("IJulia")
julia> quit()
Launch the notebook
$ jupyter notebook gp.ipynb
The notebook will try to install a few additional Julia packages itself.
If you get an error such as
IOError: [Errno 13] Permission denied: u'/Users/user/.jupyter/migrated'
============================================[ ERROR: IJulia ]=============================================
LoadError: failed process: Process(`/Users/user/.julia/v0.6/Conda/deps/usr/bin/jupyter-kernelspec install --replace --user /var/folders/zx/j_gjm0ld081b_mcqmg3gp9l1zp59y6/T/julia-0.6`, ProcessExited(1)) [1]
verify who owns the directory ~/.jupyter with ls -la ~/.jupyter. If root owns it, change ownership with
sudo chown user: ~/.jupyter/
replacing user with your username. IJulia will already be installed, so you'll need to remove IJulia and start over, or install Jupyter separately with instructions here.
