In Ubuntu 16.04.4, I installed the TensorFlow 1.3 ROCm port (for an AMD Radeon RX Vega 64) according to the instructions starting at "Install required python packages" in

https://github.com/ROCmSoftwarePlatform/tensorflow/blob/rocm-v1/rocm_docs/tensorflow-install-basic.md

where I had previously installed ROCm from the AMD Debian repository according to the instructions in

https://github.com/RadeonOpenCompute/ROCm

Then, using pip to install the TF .whl package with no virtualization:

$ wget http://repo.radeon.com/rocm/misc/tensorflow/tensorflow-1.3.0-cp27-cp27mu-manylinux1_x86_64.whl
$ sudo python -m pip install tensorflow-1.3.0-cp27-cp27mu-manylinux1_x86_64.whl

When I try to verify the installation using

$ python -c "import tensorflow as tf; print(tf.__version__)"

I get the following error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/tensorflow/__init__.py", line 24, in <module>

ImportError: libCXLActivityLogger.so: cannot open shared object file: No such file or directory

I verified that _pywrap_tensorflow_internal.so is present:

Also checked my wheel and pip versions:

$ pip list | grep wheel
wheel                        0.29.0
$ pip -V
pip 10.0.1 from ---- python2.7/site-packages/pip (python 2.7)

At first glance it looks as if some environmental variable is not set, so that _pywrap_tensorflow_internal.so is not being searched for on the correct path. Can anyone tell me if this is the case - or if the source of the problem is elsewhere? I did some searches and have come up essentially empty. Thanks in advance for any helpful responses.

Your immediate problem is that the library file libCXLActivityLogger.so is missing, since you probably never installed it. On Ubuntu, assuming that you've already added the ROCm software repository, you can obtain and install this library with:

$ sudo apt-get install cxlactivitylogger

However, you probably will then find that you are missing further libraries necessary to run TensorFlow. When you installed ROCm according to the directions at https://github.com/RadeonOpenCompute/ROCm, you only installed the "core" ROCm packages, and so you are missing some additional ROCm software components that are needed to run ROCm TensorFlow (such as MIOpen, rocRAND, rocFFT, etc.). To install these additional libraries, follow the instructions that you overlooked at:

https://github.com/ROCmSoftwarePlatform/tensorflow/blob/rocm-v1/rocm_docs/tensorflow-install-basic.md

specifically this command that will install all the needed ROCm packages to run TensorFlow:

$ sudo apt-get update && \
      sudo apt-get install -y --allow-unauthenticated \
      rocm-dkms rocm-dev rocm-libs \
      rocm-device-libs \
      hsa-ext-rocr-dev hsakmt-roct-dev hsa-rocr-dev \
      rocm-opencl rocm-opencl-dev \
      rocm-utils \
      rocm-profiler cxlactivitylogger \
      miopen-hip miopengemm
