Overview

We have recently become aware that cuda-python 11.7.1 has incorporated changes that makes it incompatible with current and legacy versions of RAPIDS when you try to install RAPIDS. You will need to pin cuda-python to 11.7.0 in conda during installation, and potentially after. An affected installation with the 11.7.1 issue results in this error being thrown:

Status

Currently, we have these two resolution paths to offer:

Resolution Path 1: You can upgrade your RAPIDS version to `v22.06.01`.  
- We've made it easy to upgrade: simply use our Release selector and install `v22.06` or rerun you `v22.06` installation script. It will automatically grab `v22.06.01` via Conda or Docker.

Resolution Path 2: If you can NOT upgrade, pin `cuda-python` to `11.7.0` in RAPIDS `v22.02`, `v22.04`, and `v22.06`, 
- You can pin `cuda-python` to `11.7.0` by using `cuda-python=11.7.0` when doing an install.  
- Example command: `conda install -c nvidia cuda-python=11.7.0`.

Older versions of RAPIDS may also be affected and users should attempt to upgrade or pin.

Impact

This issue impacts users installing conda packages of RAPIDS 22.02 through 22.06, which depend on cuda-python. This issue also affects existing conda installations of RAPIDS versions 22.02 - 22.06 if the user installs additional packages depending on cuda-python that result in an update to cuda-python>11.7.0.
