Fixed AttributeError to get io from tf

[Vivswan]

Fixed Error:
Line 72 and 86: AttributeError: module 'tensorflow' has no attribute 'io'

since:
from tensorboard.compat import tf == tensorflow
which gives AttributeError: module 'tensorflow' has no attribute 'io'
but we need:
from tensorboard.compat import tensorflow_stub as tf

now 'io' can be imported from tensorflow_stub

Sorry, next time, I will definitely open a issue first.

Python Code:

import traceback

from torch.utils.tensorboard import SummaryWriter
from tensorboard.summary.writer.event_file_writer import EventFileWriter

if __name__ == '__main__':
    print()
    print("EventFileWriter:")
    print()
    try:
        EventFileWriter("C:/X")
    except Exception as e:
        print(traceback.format_exc())

    print()
    print("SummaryWriter:")
    print()
    try:
        SummaryWriter(log_dir="C:/X")
    except Exception as e:
        print(traceback.format_exc())

Error:

Sorry, with additional testing I figured out this only happens when pytorch is installed as well. I will report the bug to pytorch then.
