ipython crashes using SFrame.read_csv

User 5308 | 6/20/2016, 4:06:12 PM

I'm evaluating GraphLab Create on Mac OS 10.11.5. When attempting to create an SFrame from an existing CSV file, the ipython session crashes:

songs = gl.SFrame.read_csv("http://s3.amazonaws.com/dato-datasets/millionsong/song_data.csv")

libc++abi.dylib: terminating with uncaught exception of type boost::archive::iterators::dataflow_exception: attempt to decode a value not in base64 char set /Users/a1152802/anaconda/envs/dato-env/bin/python.app: line 3: 68003 Abort trap: 6

I've also tried several local CSV files, all of which cause the same exception.

Hi @"Brennan Cleveland" ,

Thanks for pointing this out. We're currently trying to repro this, and we will keep you in the loop as we fix it.

Hi @"Brennan Cleveland" ,

Could you verify the python version you are using? And the GLC build number, which you can get with gl.version_info.build_number.

OK, so this is a bit of a weird error. Are you able to perform other operations, like construct an SFrame?

import graphlab sf = graphlab.SFrame()

Additionally, could you remove the ~/.graphlab directory and re-set the license key using graphlab.product_key.set_product_key()? It could be a corrupt configuration file.

Cheers! -Piotr

Re-setting the license key did the trick!

@"Brennan Cleveland" ,

Apparently operations on the .config file are non-atomic, so if multiple processes (ie. multiple python session) are trying to operate on it, there could be some file corruption.

Anyways, thanks for your patience!
