Is anyone else doing Halite III? There is a Julia starter kit on it.

Didn’t you have problem to run Julia starter bot? It just freeze in the initialization phase on my Ubuntu… ☹

I guess I am just doing something wrong (python starter bot is working like a charm).

What did you download? (me [https://halite.io/assets/downloads/Halite3\_Julia\_None.zip](https://halite.io/assets/downloads/Halite3_Julia_None.zip)) Which version of Julia (1.0.2-pre.110) do you use?

I had problem for example with

```julia
    # file networking.jl around line 17
    log(s::String, io=io) = (@info s; flush(io))

```

where Julia wanted explicitly imported `Base.log`. What did I do wrong?

I had a bit of trouble getting the halite.exe to work, missing a windows dll or unable to find it  
Best submission was around a score/rank of 39

Also there’s another comp here- [Traveling Santa 2018 - Prime Paths | Kaggle](https://www.kaggle.com/c/traveling-santa-2018-prime-paths)

If I did not start bot from hand (means outside halite(.exe) tool) then starting it through halite(.exe) I used to get something like this:

```julia
ERROR: LoadError: Failed to precompile JSON [682c06a0-de6a-54ab-a142-c8b1cf79cde6] to ~/.julia/compiled/v1.0/JSON/uf6oy.ji

```

By starting bot from hand it created ~/.julia/compiled/v1.0/JSON/uf6oy.ji and don’t need to recreate it again in competition simulation. So halite(.exe) start to work with bot.

BTW. I am surprised that in different projects (with different version dependency!) it try to create same name `uf6oy.ji` . I suspect that it could be problem to running parallel two projects with different JSON version dependencies…

Precompile into file:

```julia
julia> using JSON
[Info: Recompiling stale cache file ~/.julia/compiled/v1.0/JSON/uf6oy.ji for JSON [682c06a0-de6a-54ab-a142-c8b1cf79cde6]

```

Downgrade package:

```julia
(v1.0) pkg> pin JSON@0.19.0
 Resolving package versions...
  Updating `~/.julia/environments/v1.0/Project.toml`
  [682c06a0] ↓ JSON v0.20.0 ⇒ v0.19.0 ⚲
  Updating `~/.julia/environments/v1.0/Manifest.toml`
  [682c06a0] ↓ JSON v0.20.0 ⇒ v0.19.0 ⚲

```

Restart Julia. And now different version of JSON precompile into same file

```julia
julia> 
julia> using JSON
[Info: Recompiling stale cache file ~/.julia/compiled/v1.0/JSON/uf6oy.ji for JSON [682c06a0-de6a-54ab-a142-c8b1cf79cde6]

```

BTW I was suprised too that by `free JSON` it didn’t go back to `v0.20.0` automatically

```julia
(v1.0) pkg> free JSON
  Updating `~/.julia/environments/v1.0/Project.toml`
  [682c06a0] ~ JSON v0.19.0 ⚲ ⇒ v0.19.0
  Updating `~/.julia/environments/v1.0/Manifest.toml`
  [682c06a0] ~ JSON v0.19.0 ⚲ ⇒ v0.19.0

```
