Evaluate Perplexity: Issue when constructing DatasetReader from parameters (AWS api)

[victorelkjaer]

Dear @matt-peters et al.,
First of all: Impressive work with KnowBert!

I'd like to replicate the results based on the pretrained model and as a start: evaluate the perplexity of KnowBert-wiki.

I have followed the setup Getting Started section, downloaded the held out wiki book corpus and
set up everything in a submit script almost identical to

MODEL_ARCHIVE=..location of model
HELDOUT_FILE=wikipedia_bookscorpus_knowbert_heldout.txt
python bin/evaluate_perplexity.py -m $MODEL_ARCHIVE -e $HELDOUT_FILE

---

Having done that, I run the file, but experience a bug when I try to construct the DatasetReader from parameters after having loaded the model from the pretrained model archive knowbert_wiki_model.tar.gz. See error message below:

botocore.exceptions.ClientError: An error occurred (403) when calling the HeadObject operation: Forbidden

Before I experienced this error, I got a botocore.exceptions.NoCredentialsError: Unable to locate credentials error similar to the issue presented here: getmoto/moto#1941.
But after I created an aws configuration, I got to

botocore.exceptions.ClientError: An error occurred (403) when calling the HeadObject operation: Forbidden

Have you experienced this before? is the issue that I do not have access to the data requested in the queried s3 aws bucket?

I thank you for your time!

Best regards,
Victor

The object should be public, but you may need an S3 account to access. The files can also be downloaded via https. Does the mp/s3 branch fix the issue?

The mp/s3 branch does fix the issue, yes. Thanks @matt-peters
