Until recently, building TensorFlow at all on AArch64 was not possible due to its dependency on Bazel. Doing a bootstrap build of Bazel with its architecture-independent distribution archive failed. GitHub contributor, powderluv, has released several Bazel binaries allowing Google's instructions to work with a few caveats. Note: There are now a number of TensorFlow Docker containers for Arm but none of them are TensorFlow 2 or greater at the time of this writing.

I'm using Ubuntu 20.10 on Raspberyy Pi 4 8Gb.
After installing Bazel 3.7.0 I set (https://github.com/bazelbuild/bazelisk):
before running the bazel build.
When build finished:
It worked splendidly for me - a bit worried about the 2.5.0 version though... but at least I succeeded to install and use.
Hope it helps.
I came across following error:

Then, I found there is no ‘bazel-2.0.0-linux-arm64’ in releases.bazel.build/.../release
