Tensorflow Built from Source CustomBuilt dont Work

Question

I tried to install Rasa on a server with an Intel Xeon E5620. Rasa needs Tensorflow 14.0.0. I use an virtual Environment (Anaconda)

I have to compile Tensorflow from source, because the CPU doesn't support AVX. I created a custom Built with docker-tensorflow-builder and install it. When I tested it, I got the message:

Traceback (most recent call last):
  File "/anaconda3/envs/ki/lib/python3.6/site-packages/tensorflow/python/pywrap_tensorflow.py", line 58, in <module>

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.

See https://www.tensorflow.org/install/errors

for some common reasons and solutions.  Include the entire stack trace
above this error message when asking for help.

I fix it by install GlibC.2.30. Now i get the Error "Segmentation fault (core dumped) error". I think I get the error because Tensorflow is not adapted to my CPU. I'm not sure how to find out the appropriate compiler options and finally set them. Has anyone here experience and can help me?

This seems like a TensorFlow specific issue and has nothing to do with Rasa as such. — msamogh, Sep 12 '19 at 13:13

Here the problem is with gcc version. Please use gcc 6.4.0 for the installation of tensorflow.

Below are the steps to install Intel optimized tensorflow in conda environment.

conda create -n tf_1.10 -c intel python=3.6

source activate tf_1.10

Make sure the following lines are there in the bash_profile and source it.

export CC=/glob/development-tools/versions/gcc-6.4.0/bin/gcc

export LD_LIBRARY_PATH=/glob/development-tools/versions/gcc-6.4.0/lib64/:$LD_LIBRARY_PATH

export PATH=/glob/development-tools/versions/gcc-6.4.0/bin/:$PATH

If the path setting was successful, you should be able to see the gcc version 6.4.0 on typing gcc --version

If you get the error ImportError: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found, please follow the steps below:

mkdir ~/lib

cd ~/lib

ln -s /glob/supplementary-software/versions/glibc/glibc_2_28/lib/libm.so.6

Then export the LD_LIBRARY_PATH for it:

export LD_LIBRARY_PATH=~/lib:$LD_LIBRARY_PATH

Then, install tensorflow 1.10 using:

pip install https://storage.googleapis.com/intel-optimized-tensorflow/tensorflow-1.10.0-cp36-cp36m-linux_x86_64.whl
