NeuroNER: Trouble running main.py missing module attribute-distutils-util

Hey, thanks for the code. Unfortunately I am having difficulty running the pretrained conll_2003_en model. mu parameters.ini file looks like this:

#----- Possible modes of operation -----------------------------------------------------------------------------------------------------------------#
# training mode (from scratch): set train_model to True, and use_pretrained_model to False (if training from scratch).                        #
#				 				Must have train and valid sets in the dataset_text_folder, and test and deployment sets are optional.               #
# training mode (from pretrained model): set train_model to True, and use_pretrained_model to True (if training from a pretrained model).     #
#				 						 Must have train and valid sets in the dataset_text_folder, and test and deployment sets are optional.      #
# prediction mode (using pretrained model): set train_model to False, and use_pretrained_model to True.                                       #
#											Must have either a test set or a deployment set.                                                        #
# NOTE: Whenever use_pretrained_model is set to True, pretrained_model_folder must be set to the folder containing the pretrained model to use, and #
# 		model.ckpt, dataset.pickle and parameters.ini must exist in the same folder as the checkpoint file.                                         #

# tokenizer should be either 'spacy' or 'stanford'. The tokenizer is only used when the original data is provided only in BRAT format.
# - 'spacy' refers to spaCy (https://spacy.io). To install spacy: pip install -U spacy
# - 'stanford' refers to Stanford CoreNLP (https://stanfordnlp.github.io/CoreNLP/). Stanford CoreNLP is written in Java: to use it one has to start a
#              Stanford CoreNLP server, which can tokenize sentences given on the fly. Stanford CoreNLP is portable, which means that it can be run
#              without any installation.
#              To download Stanford CoreNLP: https://stanfordnlp.github.io/CoreNLP/download.html
#              To run Stanford CoreNLP, execute in the terminal: `java -mx4g -cp "*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer -port 9000 -timeout 50000`
#              By default Stanford CoreNLP is in English. To use it in other languages, see: https://stanfordnlp.github.io/CoreNLP/human-languages.html
#              Stanford CoreNLP 3.6.0 and higher requires Java 8. We have tested NeuroNER with Stanford CoreNLP 3.6.0.

Any ideas?
