Trouble with webppl-csv

[Isaac Davis]

Hi folks. I am new to webppl and trying to get the webppl-csv package to work.

I wrote a simple test file that generates a data table and outputs it using the command

csv.write(d, 'test/test-file-copy.csv');

I ran the file using the command

webppl h22_code.txt --require webppl-csv

(h22_code.txt is the name of the test file)

I get the following error message, and I have no idea what this means.

Any advice or suggestions would be greatly appreciated, thanks!

Hi. I'm not sure what's happening here, but if you can make a stand alone program that I can run locally to easily reproduce the problem I'll happily take a closer look for you.

Cheers,

Hi Paul. I've attached the file here. I tried to keep it as simple as humanly possible- it creates an array and writes it to a csv file in the same directory.

Thanks!

Thanks. It seems to work if you make the thing you're serializing a nested array. e.g. This works for me:

var test=[0,1,1,2,1];

csv.write([test,test], 'test-file.csv');

Yes that seemed to work! I think I need to play around with the array formatting.

Thanks so much!
