Get ValueError when the Input format is line

[imgarylai]

When I use line as input format for sentiment analysis. I got this error message.

ValueError: Error when checking : expected input_2 to have 3 dimensions, but got array with shape (0, 1)

The code I executed is

from elit.decode import EnglishDecoder, DOC_DELIM
from elit.util.configure import *

# Please replace the correct resource path.
RESOURCE_PATH = os.path.join('resources')
local_filename = "test.txt"

config = Configuration(tokenize=True, input_format='line', segment=True, sentiment=(SENTIMENT_TWITTER, SENTIMENT_MOVIE))

nd = EnglishDecoder(resource_dir=RESOURCE_PATH, config=config)

with open(local_filename, 'r', encoding='utf8') as f:
    result = nd.decode(config, StringIO(f.read()))

The file, test.txt, I tested:
