Troubles with bazel and building tensorflow on ubuntu - tensorflow

Question

I'm trying to build tensorflow on ubuntu using bazel, I failed using bazelisk and bazel. There is some silly bug with the installer. I'm really having hard time because of the awful documentation of building tensorflow from source found here
wget https://github.com/bazelbuild/bazel/releases/download/0.27.1/bazel-0.27.1-installer-linux-x86_64.sh
chmod +x bazel-0.27.1-installer-linux-x86_64.sh
./bazel-0.27.1-installer-linux-x86_64.sh --user
export PATH="$PATH:$HOME/bin"
git clone https://github.com/tensorflow/tensorflow
cd tensorflow
./configure
Out:
INFO: Options provided by the client:
Inherited 'common' options: --isatty=1 --terminal_columns=80
INFO: Reading rc options for 'version' from /home/emadboctor/tensorflow/.bazelrc:

raise CalledProcessError(retcode, cmd, output=output)
subprocess.CalledProcessError: Command '['bazel', '--batch', '--bazelrc=/dev/null', 'version']' returned non-zero exit status 2
And this keeps happening with version 0.25.1 and 0.19.1
and when I try this version of installation:
sudo apt install curl
curl https://bazel.build/bazel-release.pub.gpg | sudo apt-key add -
echo "deb [arch=amd64] https://storage.googleapis.com/bazel-apt stable jdk1.8" | sudo tee /etc/apt/sources.list.d/bazel.list
sudo apt update && sudo apt install bazel
sudo apt update && sudo apt full-upgrade
sudo apt install bazel-1.0.0
cd tensorflow
./configure
This issue comes up:
Traceback (most recent call last):
File "./configure.py", line 1553, in <module>

File "./configure.py", line 1370, in main

subprocess.CalledProcessError: Command '['bazel', '--batch', '--bazelrc=/dev/null', 'version']' returned non-zero exit status 1
So I try following the guide found here
sudo apt update
sudo apt dist-upgrade
sudo apt install git openjdk-8-jdk curl
sudo apt install python3-dev python3-pip python3-numpy
sudo apt install pkg-config zip g++ zlib1g-dev unzip
wget https://github.com/bazelbuild/bazel/releases/download/0.19.2/bazel-0.19.2-installer-linux-x86_64.sh
chmod +x bazel-0.19.2-installer-linux-x86_64.sh
sudo ./bazel-0.19.2-installer-linux-x86_64.sh
sudo swapoff /swapfile
sudo fallocate -l 16G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
git clone https://github.com/tensorflow/tensorflow.git
cd tensorflow
git checkout r2.1
Same error as before:

subprocess.CalledProcessError: Command '['bazel', '--batch', '--bazelrc=/dev/null', 'version']' returned non-zero exit status 2
so I try bazelisk(and this is supposed to install the correct version of bazel):
Here are the exact steps:
sudo apt-get update && sudo apt-get upgrade
sudo apt install python-dev python-pip # or python3-dev python3-pip
pip install -U --user pip six numpy wheel setuptools mock 'future>=0.17.1'
pip install -U --user keras_applications --no-deps
pip install -U --user keras_preprocessing --no-deps
then I install go using this
cd /tmp
wget https://dl.google.com/go/go1.11.linux-amd64.tar.gz
sudo tar -xvf go1.11.linux-amd64.tar.gz
sudo mv go /usr/local
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH
source ~/.profile
Then I install bazelisk using this
go get github.com/bazelbuild/bazelisk
export PATH=$PATH:$(go env GOPATH)/bin
then I try to configure again:
git clone https://github.com/tensorflow/tensorflow.git
cd tensorflow
./configure
Out:

raise CalledProcessError(retcode, cmd, output=output)
subprocess.CalledProcessError: Command '['bazel', '--batch', '--bazelrc=/dev/null', 'version']' returned non-zero exit status 2
Then I retry this, I get new error:
Extracting Bazel installation...
WARNING: --batch mode is deprecated. Please instead explicitly shut down your Bazel server using the command "bazel shutdown".
You have bazel 0.19.2 installed.
Please upgrade your bazel installation to version 0.27.1 or higher to build TensorFlow!
So I install 0.27.1 in the following way:
wget https://github.com/bazelbuild/bazel/releases/download/0.27.1/bazel-0.27.1-installer-linux-x86_64.sh
chmod +x bazel-0.27.1-installer-linux-x86_64.sh
./bazel-0.27.1-installer-linux-x86_64.sh --user
export PATH="$PATH:$HOME/bin"
cd tensorflow
./configure
I get the same error even after installing the required version
WARNING: --batch mode is deprecated. Please instead explicitly shut down your Bazel server using the command "bazel shutdown".
You have bazel 0.19.2 installed.
Please upgrade your bazel installation to version 0.27.1 or higher to build TensorFlow!
and this is the output of bazel version:

Answer 1

Your checkout of the Tensorflow source code requires Bazel 2.0.0, because of the use of the --experimental_repo_remote_exec flag.
Also see https://github.com/tensorflow/tensorflow/issues/37474
You almost got it right with bazelisk. go get github.com/bazelbuild/bazelisk installs bazelisk as bazelisk. Instead, download bazelisk, and create a symlink at ~/bin/bazel to point to bazelisk. This way, TensorFlow's configure script can successfully pick up bazelisk as bazel.
go get github.com/bazelbuild/bazelisk
mkdir -p ~/bin
ln -s $(go env GOPATH)/bin/bazelisk ~/bin/bazel
export PATH=$HOME/bin:$PATH
