Tensorflow AttributeError：'NoneType'对象没有属性'TF_DeleteStatus'

Question

Tensorflow is giving me this unresolved error:

Exception ignored in: <bound method BaseSession.__del__ of <tensorflow.python.client.session.Session object at 0x7f68d14b6668>>
Traceback (most recent call last):
  File "/opt/anaconda3/lib/python3.5/site-packages/tensorflow/python/client/session.py", line 532, in __del__
AttributeError: 'NoneType' object has no attribute 'TF_DeleteStatus'

The error has been discussed here . The problem is it is not showing up consistently. However, it is showing up in my terminal frequently. Has anybody managed to get around it.Thanks.

Answer 1

You can run import gc; gc.collect() import gc; gc.collect() in the end of your code.

Answer 2

You need to delete the Tensorflow session to avoid that message. The simplest probably is to use a with statement:

from keras import backend as K

def main():
    with K.get_session():
        train()
        classify()

Answer 3

Answer from Github posted here to save time:

from keras import backend as K

# ... code
K.clear_session()

I added the K.clear_session() right before the model.load_weights call in my code and that worked.

Answer 4

write code in your tensorflow keras model...

from keras import backend as K
.
.
.
.
.
model.load_weights("modelname")
K.clear_session()
