YAMLLoadWarning while using quality-filter q-score-joined

Dear q2 tech support,

I am getting the following error when using qiime quality-filter q-score-joined with --verbose flag. I am using qiime-2019.4. I get the same error when using qiime-2019.7.

/home/[email protected]/miniconda3/envs/qiime2-2019.4/lib/python3.6/site-packages/q2_quality_filter/_filter.py:88: YAMLLoadWarning: calling yaml.load() without Loader=… is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
phred_offset = yaml.load(metadata_view)[‘phred-offset’]

The webpage https://github.com/yaml/pyyaml/wiki/PyYAML-yaml.load(input)-Deprecation explains why its deprecated, how to stop this warning, and says that the function should still work. However, qiime quality-filter q-score-joined with the --verbose flag has been running for a long time and there is no standard output. Is there an issue or should the function work fine? top shows that qiime is runing using 100% CPU and 0.1% MEM

Thanks!

Patience rewards. Just had to wait… It would be great of--verbose actually did output info.
