How to raise an exception for a tensorflow out of memory error

问题

I am running several tensorflow inferences using sess.run() in a loop and it happens that some inferences are too heavy for my GPU.

I get errors like :

2019-05-23 15:37:49.582272: E tensorflow/core/common_runtime/executor.cc:623] 
Executor failed to create kernel. Resource exhausted: OOM when allocating tensor of shape [306] and type float

I would like to be able to catch these specific OutOfMemory errors but not other errors (which may be due to a wrong input format or a corrupted graph.)

Obviously, a structure similar to :

try:
   sess.run(node_output, feed_dict={node_input : value_input})
except:
    do_outOfMemory_specific_stuff()

does not work since other kind of errors will lead to a call to the do_outOfMemory_specific_stuff function.

Any idea how to catch these OutOfMemory errors ?

回答1:

You should be able to catch it via:

...
except tf.errors.ResourceExhaustedError as e:
    ...

according to this documentation.
