Turning off warnings on tensorflow 1.7

[martincousi]

When running tffm on tensorflow 1.7, the following warning appears:

WARNING:tensorflow:Variable += will be deprecated. Use variable.assign_add if you want assignment to the variable value or 'x = x + y' if you want a new python Tensor object

How is it possible to turn it off? I think that these are coming from core. init_main_block() and core. init_regularization()...
