[BUG]: PyCall.jl doesn't convert pyobject to Julia array when run in Juno

[andreyzhitnikov]

Details

• Atom version: 1.47.0
• Julia version:1.4.1
• OS:Ubuntu 18.4
• Package versions:
  • Atom.jl: v0.12.11
  • julia-client: 0.12.5
  • ink: 0.12.4

Steps to reproduce

1. in Juno:
   using PyCall
   np = pyimport("numpy")
   a= np.zeros(3)

a stays PyObject

2.In REPL:
a= np.zeros(3)
3-element Array{Float64,1}:
0.0
0.0
0.0

I can't repro this (with [email protected])

using PyCall
const np = pyimport("numpy")
a = np.zeros(3) # => Vector{Float64} with 3 elements

@aviatesk I believe this bug still exists and can be reproduced with the following

using PyCall
const np = pyimport("numpy")
a = np.zeros(3)
b = Array(a)

a remains a PyObject and won't be converted to Array when debugging.

Package versions are as follows

  [c52e3926] Atom v0.12.15
  [e5e0dc1b] Juno v0.8.2
  [438e738f] PyCall v1.91.4

Could you try you can also reproduce this, e.g. using Debugger.jl or other JuliaInterpreter-based debugger ? I guess it's an upstream issue.

@aviatesk Thanks! It seems to be an upstream issue. I got it replicated in REPL using Debugger.jl. Going to post an issue to the upstream

using Debugger
using PyCall

       np = pyimport("numpy")
       a = np.zeros(3)
       b = Array(a)
       end

cool, here is where you want to post it: https://github.com/JuliaDebug/JuliaInterpreter.jl/issues
