ResourceLoadException: glacier.MultipartUpload has no load method

I can not access some resources that should be possible to access on multipart uploads

>>> import sys, boto3, botocore
>>> sys.version, boto3.__version__, botocore.__version__
('3.6.0 (default, Dec 28 2016, 19:53:26) \n[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)]', '1.4.4', '1.5.43')
>>> glacier = boto3.resource('glacier')
>>> vault = glacier.Vault(account_id=my_account_id, name=my_vault_name)
>>> multipart_upload = vault.initiate_multipart_upload(partSize=str(1024*1024))
>>> multipart_upload.id
'z8GLq4AvfwswiutS8VD2ilGpb4P4iJ8QvRuRntuleU55OlYzn2WOruz5SodZjbtgyISLtsuM0kiLfr9J5Vy6vUE46ZJc'
>>> multipart_upload.part_size_in_bytes
Traceback (most recent call last):

boto3.exceptions.ResourceLoadException: glacier.MultipartUpload has no load method

I’m not sure if this is related, but I also noticed a typo in the client with this collection, that might possibly be related or causing the problem above

>>> vault.multipart_uplaods.all()   # sic
glacier.Vault.multipart_uplaodsCollection(glacier.Vault(account_id='1234', name='example'), glacier.MultipartUpload)
