InexactError: check_top_bit(Int32, -1)

[J-Massey]

Good afternoon, I'm very new to julia (within the week) and am trying to plot a couple of things with pyplot as that's what I'm familiar with. I've added the PyPlot package but when I try and load it into my script I get this error:

LoadError: InexactError: check_top_bit(Int32, -1) in expression starting at /home/masseyjmo/Workspace/Lotus/projects/vforce/velocity_profiles/blasius.jl:6 throw_inexacterror(::Symbol, ::Any, ::Int32) at boot.jl:567 check_top_bit at boot.jl:581 [inlined] toUInt64 at boot.jl:691 [inlined] Type at boot.jl:722 [inlined] _jl_spawn(::String, ::Array{String,1}, ::Cmd, ::Tuple{Base.PipeEndpoint,Base.TTY,RawFD}) at process.jl:347

Have you got any advice?

Thanks, Jonah

All that was required was a quick restart and I was away
