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.
