**How severe does this issue affect your experience of using Ray?** - High: It blocks me to complete my task. Is it possible to get Rllib on power-9 linux architecture? I’ve tried installing the wheels but it tells me that they are not supported on my platform. I’m essentially wondering if I’m missing something (e.g. can source+compile pip packages be installed somehow? Are there any stories of people successfully installing on power-9?), which could allow me to avoid building from source manually (I also am unsure if it is possible to use docker on my system). So far I’ve tried both the [anaconda package](https://anaconda.org/conda-forge/ray-rllib) & pip, but nothing more advanced than that. P.S. I see that Rlib [at least advertises](https://docs.ray.io/en/latest/cluster/lsf.html) support for IBM HPC clusters. This seems to imply that it _should_ work on power9 right? ---

Hey @Prof_Plum , thanks for this question. I changed to topic to “Ray Core” for better matching. @Clark_Zinzow , could you or someone from your team answer this question? Thanks 🙂 ---

Hi @Prof_Plum Ray doesn’t have official support for power-9 architecture. I haven’t heard other users installing on power-9. One thing you may try is to build Ray on your power-9 machine. You can find the steps at here (for other architectures): [Building Ray from Source — Ray 2.0.0.dev0](https://docs.ray.io/en/master/ray-contribute/development.html#building-ray), which may serve as a reference to build on power-9. ---

I’m looking into this as well. It seems like [building python only](https://docs.ray.io/en/master/ray-contribute/development.html#building-ray-python-only) won’t be an option on power 9 architectures since the wheel (pip install -U [https://s3-us-west-2.amazonaws.com/ray-wheels/latest/ray-2.0.0.dev0-cp38-cp38-manylinux2014\_x86\_64.whl](https://s3-us-west-2.amazonaws.com/ray-wheels/latest/ray-2.0.0.dev0-cp38-cp38-manylinux2014_x86_64.whl)) is not for Power 9. So it seems we’ll have to try a full build. I’ll give this a try and update as I make progress. ---

I’ve been hinderd by the need for sudo in order to build ray from scratch. I won’t be able to get this on my machine, so it’s unlikely I’ll be able to make more progress here. Sorry ☹
