powerai:1.5.4 Tensorflow

Hi,

I am trying to use ibmcom/powerai:1.5.4-all-ubuntu18.04-py3 since it's listed as having TF 1.12.0, which is required for code I am trying to run.

I've also tried source /opt/DL/tensorflow/bin/install_dependencies then source /opt/DL/tensorflow/bin/tensorflow-activate as recommended from a similar issue, but attempting import tensorflow still fails with ImportError: libcuda.so.1: cannot open shared object file: No such file or directory

The architecture is ppc64le.

I think we weren't shipping CUDA as part of PowerAI back in the 1.5.4 timeframe, so that needed to be downloaded directly from NVIDIA and installed separately as a pre-requisite to PowerAI itself.

There's some info in the System Setup section of the 1.5.4 docs: https://www.ibm.com/support/knowledgecenter/SS5SF7_1.5.4/navigation/pai_systemsetup.html

Note each version of PowerAI was built against specific CUDA version, and for 1.5.4 that was CUDA 10.0. That may limit the RHEL versions you could install on. The GPU driver version is a bit more flexible--generally newer driver versions should support older CUDA versions. But you'd still need a RHEL OS, CUDA, and driver version that are all supported together.

Right. Can you share your CUDA installation details?
Do you have nvidia-docker setup properly? (Does nvidia-smi work from inside the container?)

I am working on a provided machine so I have very restricted permissions, i.e. no installation.

OS is Ubuntu 16.04, CUDA is at 9.2:

$ nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2018 NVIDIA Corporation
Built on Tue_Jun_12_23:08:37_CDT_2018
Cuda compilation tools, release 9.2, V9.2.148

nvidia-docker is also installed but I am not sure about the setup:

$ nvidia-docker --version
Docker version 18.03.1-ce, build 9ee9f40

nvidia-smi works outside the container, but not inside.

OK, it sounds like your nvidia-docker set up is not working.
What is the output of docker info ?
