Hi @Jenna_Shelton! This sounds like an out-of-memory error, but to help diagnose, can you please attach the detailed error log (it should be the filepath mentioned just past the bottom of your screenshot). Alternatively, you can re-run with --verbose. If it is a memory error, you could try adding the pre_dispatch parameter, and set it to 1 (by default it is 2*n_jobs, or you could try reducing the default chunk_size, which might help. Thanks!
