tf.debugging.Assert
Asserts that the given condition is true.
tf . debugging . Assert (
condition , data , summarize = None , name = None
)
If condition
evaluates to false, print the list of tensors in data
.
summarize
determines how many entries of the tensors to print.
Note: In graph mode, to ensure that Assert executes, one usually attaches
a dependency:
# Ensure maximum element of x is smaller or equal to 1
assert_op = tf . Assert ( tf . less_equal ( tf . reduce_max ( x ), 1. ), [ x ])
with tf . control_dependencies ([ assert_op ]):
... code using x ...
Args
condition
The condition to evaluate.
data
The tensors to print out when condition is false.
summarize
Print this many entries of each tensor.
name
A name for this operation (optional).
Note: The output of this function should be used. If it is not, a warning will be logged or an error may be raised. To mark the output as used, call its .mark_used() method.
