ERROR: LoadError: UndefVarError: DataArrays not defined

[mjk0s1ba]

Can anyone help me with this error code?

@mjk0s1ba

DataArrays is a package. So to fix the error first you need to run

Pkg.add("DataArrays")

in Julia, then in the data_cleaning.jl file you need to add the following to the top of the document

using DataArrays

That should solve your issue.

Thank you. That got me further along, but still got an error on the output. The way I finally got it to work was to comment out some of the output variables. See below:

path_to_output= #=string(string(formulation), "stacksize", stack_size,"overlap", num_overlap,"lineups", num_lineups,=#"C:/Users/Michael/.julia/mlb/output.csv";

path_to_output_proj = #=string("proj_baseball_", string(formulation), "stacksize", stack_size,"overlap", num_overlap,"lineups", num_lineups,=#"C:/Users/Michael/.julia/mlb/output_proj.csv";

path_to_output_actual = #=string("actual_baseball_", string(formulation), "stacksize", stack_size,"overlap", num_overlap,"lineups", num_lineups,=#"C:/Users/Michael/.julia/mlb/output_actual.csv";

@mjk0s1ba I'm not sure on PC how it works but I have my folders saved outside of the julia install and it looks like this in my code:

path_pitchers = "/Users/escism/Desktop/DFS/Baseball/2016-08-12 pitchers.csv"
path_hitters = "/Users/escism/Desktop/DFS/Baseball/2016-08-12 hitters.csv";

@jnederlo Thank you for the Using DataArrays, that got me to the next error which says:

ERROR: LoadError: Invalid Gurobi license

I have looked at the baseball_formulations.jl file and tried to comment out the Using Gurobi code on line 20, but that doesne't seem to make a difference. Any add'l guidance would greatly appreciated!

[jnederlo]

@escism you have to comment out line 40, not line 20, but no harm in commenting out line 20 either.

#uncomment this line only if you are using Gurobi, which costs money :(), but is super fast :) # m = Model(solver=GurobiSolver(OutputFlag=0))

[escism]

@jnederlo Excellent! Thanks for the update now it ran perfectly!

@escism @jnederlo if you still have this working, could you please comment in #8 with what versions of the packages you are running? The output of Pkg.status() on a working instance would be super helpful. It seems as though the latest versions of these packages no longer play nice together. I have found that I must pin julia to 0.4.0 or a 0.6 version, and JuMP to 0.12.1, but still run into errors loading Calculus
