TensorFlow.jl how to use visualize?

General Usage

I watched the juliacon video on TensorFlow.jl and found it quite cool. So I tried to reproduce the examples.
In the video the visualize function is used… If I try to do the same thing on my machine I get an error however:

could not spawn `tensorboard --logdir=/tmp/tmpdXvsXU --port=6006`: no such file or directory (ENOENT)

Stacktrace:
 [1] _jl_spawn(::String, ::Array{String,1}, ::Ptr{Void}, ::Base.Process, ::Base.DevNullStream, ::Base.PipeEndpoint, ::Ptr{Void}) at ./process.jl:360

Is this expected? To install TensorFlow I simply did

Pkg.add("TensorFlow")
Pkg.checkout("TensorFlow")
Pkg.build("TensorFlow")

Do I have to install tensorboard manually or something?

Hey, thanks for checking out TensorFlow.jl! I really appreciate it.

Can you file an issue on https://github.com/malmaud/TensorFlow.jl? The issue is that you do have tensorboard, but it’s not in the system path. I’ll revise TensorFlow.jl to take that possibility into account.

Thanks for the quick answer!

Can you suggest some workaround until this is fixed?

In case other people face the same problem, the following hack works for me:

path = joinpath(Pkg.dir("Conda"), "deps", "usr", "bin")
if !contains(ENV["PATH"], path)
    ENV["PATH"] = string(ENV["PATH"], ":", path)
end
