MXNet Nightly Builds Moved to S3

[szha]

Hi,

MXNet nightly builds have been moved from PyPI to S3 (pypi/support#243). If this project requires the nightly builds for CI validation, please make sure that your CI pipeline now takes the nightly builds from https://dist.mxnet.io/python. Furthermore, as MXNet 1.7 and 2.0 are currently in progress simultaneously, we are releasing nightly builds for both 1.x and 2.x. Take mxnet-cu102 for example:

If you need the nightly builds for 1.x:

pip install --pre "mxnet-cu102<2" -f https://dist.mxnet.io/python

If you need the nightly builds for 2.x:

pip install --pre "mxnet-cu102>=2" -f https://dist.mxnet.io/python

Feel free to close this issue if the necessary changes have been made, or If the project doesn't rely on MXNet nightly builds. Thanks.
