Precompilation Error

[thecoldviews]

After running a recent Pkg.update(), I am unable to use BasicPOMCP. -

using BasicPOMCP

Hi @thecoldviews , thanks for reporting the problem! Unfortunately I haven't been able to reproduce it.

It looks like you might somehow have an older version of POMDPToolbox. What is the output of

julia> Pkg.installed("POMDPToolbox")

?

If that doesn't reveal anything, what is the output of

julia> run(`git -C $(Pkg.dir("MCTS")) status`); run(`git -C $(Pkg.dir("BasicPOMCP")) status`)

?

Thanks!

Hi @zsunberg! Thanks for the prompt response. For the first command, the output is

v"0.2.4"

and for the second it is

Your branch is up-to-date with 'origin/master'.

nothing to commit, working directory clean
On branch master
Your branch is up-to-date with 'origin/master'.

nothing to commit, working directory clean```

To run POMCP, you need POMDPToolbox v0.2.6

Not sure why you don't have it if you did Pkg.update()

Hey! I pinned the version to v0.2.6 and now it's working. Thanks! Still not able to figure out why I ran into the issue after a Pkg.update(), reading the logs it seems like it had to do with some dependency imposed by another Package I was using. Closing it though.

Ah, yeah, there were breaking changes introduced in DataFrames version 0.11. POMDPToolbox requires DataFrames >= 0.11 and Gadfly requires DataFrames < 0.11.
