Installing Bazel

The Bazel tool is required for TensorFlow compilation. TensorFlow 2.13.0 depends on Bazel 5.4.0. Download the correct Bazel version.

  1. Use PuTTY to log in to the server as the root user.
  2. Download the Bazel 5.4.0 source code to the server.

    https://github.com/bazelbuild/bazel/releases/download/5.4.0/bazel-5.4.0-dist.zip

    If the server is connected to the Internet, you can run the wget command to download the source code package.

    1
    wget https://github.com/bazelbuild/bazel/releases/download/5.4.0/bazel-5.4.0-dist.zip --no-check-certificate
  3. Install dependencies for Bazel.
    1
    yum install java-11-openjdk java-11-openjdk-devel

    Check whether OpenJDK 11 is successfully installed.

    1
    java -version

    If the preceding information is displayed, the installation is successful.

    An earlier OpenJDK version may cause an error during Bazel compilation.

  4. (Optional) If the preceding command output displays an incorrect version, configure environment variables.
    1. Search for the installation directory.
      1
      find / -name java
    2. Configure environment variables. Assume that the installation directory is /usr/lib/jvm/java-11-openjdk-11.0.21.9-1.oe2203sp3.aarch64.
      • Method 1 (effective permanently):
        1
2
3
        echo "export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-11.0.21.9-1.oe2203sp3.aarch64" >> /etc/profile
echo "export PATH=\${JAVA_HOME}/bin:\${PATH}" >> /etc/profile
source /etc/profile
      • Method 2 (effective for the current session):
        1
2
        export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-11.0.21.9-1.oe2203sp3.aarch64
export PATH=/usr/lib/jvm/java-11-openjdk-11.0.21.9-1.oe2203sp3.aarch64/bin:$PATH
    3. Check the OpenJDK version.
      1
      java -version
  5. Decompress, compile, and install Bazel.
    1
2
3
    unzip bazel-5.4.0-dist.zip -d bazel
cd bazel
env EXTRA_BAZEL_ARGS="--tool_java_runtime_version=local_jdk" bash ./compile.sh
  6. Create a soft link.
    1
    ln -s ${Bazel root directory}/output/bazel /usr/bin/bazel

    Replace ${Bazel root directory} with the actual directory. If the Baszel source code path is /path/to/bazel, the actual command is ln -s /path/to/bazel/output/bazel /usr/bin/bazel.

  7. Check whether the installation is successful.
    1
    bazel --version

    If the correct version is displayed, the installation is successful.
