Refer to a managed folder as a folder instead of individual files

Hi all,

I'm running into a problem while setting up a BERT model script in a text classification task/flow. The Huggingface transformers take a path of a folder containing multiple files as input. This works fine when testing locally, but the architecture of Dataiku forces me to use managed folder in which the language model (BERT transformer) files reside and I see no easy way of giving the managed folder as input. Is there a common solution for this?  Below is a solution I've tried:

 

from transformers import BertTokenizer, BertModel
import dataiku

#Path to the language model managed folder
LM_FOLDER_NAME = 'LM'
LM_FOLDER = dataiku.Folder(LM_FOLDER_NAME)
LM_PATH = LM_FOLDER.get_path()

tokenizer = BertTokenizer.from_pretrained(LM_PATH + "/output_large")
bert_model = BertModel.from_pretrained(LM_PATH + "/output_large")

 

However, the code above gives the following error:

---------------------------------------------------------------------------

PermissionError: [Errno 13] Permission denied: '/home/dssuser'

As get_download_stream() works for files specifically this is of little help as I need the entire folder -> 'output_large'. Any help would be welcome!

Thanks!

Hi,

the /home/dssuser isn't accessible to the UNIX users running recipes or notebooks in DSS, so you need to grant at least traversal up to the DSS datadir, starting with a `chmod 755 /home/dssuser`
