[QST] Installing RAPIDS 24.06 not recognizing UCX version

[stephwon]

I was trying to install rapids 24.06 but give this error message

warning  libmamba Problem type not implemented SOLVER_RULE_STRICT_REPO_PRIORITY
failed

LibMambaUnsatisfiableError: Encountered problems while solving:
  - package rapids-24.06.00-cuda11_py310_240605_g9ea7562_0 requires ucx >=1.15.0,<1.16.0, but none of the providers can be installed

Could not solve for environment specs
The following package could not be installed
└─ rapids 24.06**  is not installable because it requires
   └─ ucx >=1.15.0,<1.16.0 , which conflicts with any installable versions previously reported.

When I ran the conda search ucx --channel conda-forge
it has 1.15.0 and 1.16.0 so I am not sure why it will not install rapids 24.06

My conda version is 24.1.2, python 3.11.7
virtual packages:

virtual packages : __archspec=1=zen3
                          __conda=24.1.2=0
                          __cuda=12.4=0
                          __glibc=2.35=0
                          __linux=5.15.0=0
                          __unix=0=0

How can I address this problem?

Same problem, any solutions?

Hi @pacificoceanmist & @Chevolier,

Can you please share the install command you are running? And can you share the output of conda config --show?

One potential issue is that the channel priority is set to strict which is not currently supported by RAPIDS installs.

[stephwon]

@raydouglass this is the installation command
conda create -n rapids-24.08 -c rapidsai -c conda-forge -c nvidia \ rapids=24.08 python=3.11 'cuda-version>=12.0,<=12.5'
I copied the command from here.

conda config --show is showing me this:

I can see that the channel_priority: strict Will changing the channel priority to flexible fix the problem? Or are there more that I need to do or reconfigure....

Yes, I suspect changing to flexible will work. If it doesn't please let us know the new error and we can check into it.
