I tried to install TnsorFlow from source seeing the official page [1].
The source is on GitHub [2].
Install build dependency RPM packages
$ sudo dnf install python-devel
Install a build tool Bazel.
Bazel is necessary to build TensorFlow from the source.
I did it seeing [3]. It is not registered on the Fedora official repository.
$ sudo dnf copr enable vbatts/bazel $ sudo dnf install bazel $ rpm -q bazel bazel-0.12.0-1.fc27.x86_64
Build TensorFlow from the source
This time I tried to install it to virtualenv Python environment.
$ git clone git@github.com:tensorflow/tensorflow.git $ cd tensorflow $ python3 --version Python 3.6.2 $ python3 -m venv ./venv
It seems that the configure script does not have options.
At least I could not see those by ./configure --help. Maybe there is another way to specify the options.
Answering Yes/No interactively is not so easy.
This time I did as default typing Enter key.
(venv) $ ./configure Invalid python path: y cannot be found. Please specify the location of python. [Default is /home/jaruga/git/tensorflow/venv/bin/python]: Do you wish to build TensorFlow with jemalloc as malloc support? [Y/n]: jemalloc as malloc support will be enabled for TensorFlow. Do you wish to build TensorFlow with Google Cloud Platform support? [Y/n]: Google Cloud Platform support will be enabled for TensorFlow. Do you wish to build TensorFlow with Hadoop File System support? [Y/n]: Hadoop File System support will be enabled for TensorFlow. Do you wish to build TensorFlow with Amazon S3 File System support?

[y/N]: No VERBS support will be enabled for TensorFlow. Do you wish to build TensorFlow with OpenCL SYCL support? [y/N]: No OpenCL SYCL support will be enabled for TensorFlow. Do you wish to build TensorFlow with CUDA support? [y/N]: No CUDA support will be enabled for TensorFlow. Do you wish to download a fresh release of clang? (Experimental) [y/N]: Clang will not be downloaded. Do you wish to build TensorFlow with MPI support? [y/N]: No MPI support will be enabled for TensorFlow. Please specify optimization flags to use during compilation when bazel option "--config=opt" is specified [Default is -march=native]: Preconfigured Bazel build configs. You can use any of the below by adding "--config=<>" to your build command. See tools/bazel.rc for more details. --config=mkl # Build with MKL support. --config=monolithic # Config for mostly static monolithic build. Configuration finished
Install the build dependency.
(venv) $ pip install -U six numpy wheel
Build TensorFlow. Below "bazel build" command creates build_pip_package script file. The build time is really long. It took 8993 sec (= 2h 29 min).
(venv) $ bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package ... INFO: Elapsed time: 8993.363s, Critical Path: 116.11s INFO: Build completed successfully, 8971 total actions
Below command creates package file by created script file build_pip_package.
There are many warnings.
This step might have issue on my environment.

raise ImportError("Could not import tensorflow. Do not import tensorflow "
ImportError: Could not import tensorflow. Do not import tensorflow from its source directory; change directory to outside the TensorFlow source tree, and relaunch your Python interpreter from there.
Ah the error message shows the reason of the error clearly.
Do not import tensorflow from its source directory; change directory to outside the TensorFlow source tree,

Okay!!
