As a simple POC to test distribution, you can try installing MXNet based on these 3 URLs:
pip install --no-cache-dir https://mxnet-dev.s3.amazonaws.com/mxnet_cu101-1.5.1.post0-py2.py3-none-manylinux1_x86_64.whl pip install --no-cache-dir https://mxnet-dev.s3-accelerate.amazonaws.com/mxnet_cu101-1.5.1.post0-py2.py3-none-manylinux1_x86_64.whl pip install --no-cache-dir https://d19zq12jzu4w95.cloudfront.net/ mxnet_cu101-1.5.1.post0-py2.py3-none-manylinux1_x86_64.whl where --no-cache-dir prevents caching the downloaded file, for the purpose of testing. (cu101 chosen based on large size) The first URL uses standard S3 bucket in US. The second uses S3 Accelerate based on CloudFront CDN. And the third uses CloudFront CDN. I'm adding the third URL, as S3 Accelerate may or may not use all new CloudFront endpoints yet. Regarding voting: Uploading to Pypi is currently impossible, which is a reality (so there is no option to continue as we do currently). Pypi folks indicated they will unblock our uploads to Pypi once we stop uploading nightly releases and taking up 20% of their ressources [1]. If there are any shortcomings or problems identified with uploading to S3, we can work to address them. But for now, status quo is broken and this seems the only solution addressing Pypi's problem. I don't mind if you state that you object to lazy consensus and start a vote. If your "maybe [...] start a proper vote" was supposed to be an objection to lazy consensus, please state so clearly (I'm not sure if "maybe" qualifies as objection). Though I think it only makes sense with at least 2 options to vote on. Status quo is not a meaningful option, as it is already broken.
