I watched the juliacon video on [TensorFlow.jl](https://github.com/malmaud/TensorFlow.jl) and found it quite cool. So I tried to reproduce the examples.  
In the [video](https://youtu.be/MaCf1PtHEJo?t=370) the visualize function is used… If I try to do the same thing on my machine I get an error however:

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

Stacktrace:

```

Is this expected? To install TensorFlow I simply did

```julia
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](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.

Can you suggest some workaround until this is fixed?

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

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

```
