fix mxnet version check like '0.9.3a3'

[lryta]

What about changing it to

import re
...
current = tuple(int(re.match(r'^\d+',v).group()) for v in mx.__version__.split("."))

It is possible to have 0.10.11a8.

@lryta You are right.

[lryta]

It looks like lint fails. Please add a space between r'^\d+' and v:

re.match(r'^\d+',v) => re.match(r'^\d+', v)

Thank you!
