This appears in linting using the docker scripts. I'm not sure
why this isn't failing in the standard CI for TVM and it might
be that the docker images haven't been updated in the CI system.

python3 -m pylint vta/python/vta --rcfile=/workspace/tests/lint/pylintrc

C:131, 4: Missing method docstring (missing-docstring)

http://www.trieuvan.com/apache//creadur/apache-rat-0.12/apache-rat-0.12-bin.tar.gz
gives a 404 so point the installer at archive.apache.org hopefull that
is more reliable.

* Stop use Select

* Remove Select

* TreeNode refactor

* Change entry_func name

* Remove Cmp due to rebase issue

- Weight dtype can be different than idtype. So, using the weight tensor to set
the dtype of weight.
- For conv2d NCHWc operator, the weight can be of any dimension. For int8
computation on Intel, it can be 7D. Relaxing the weight type checking.
