NotFoundError (see above for traceback): Key Variable not found in checkpoint

[gr8Adakron]

Hey,

I got the error while running this running the following command:

WARNING:tensorflow:From /home/gr8-adakron/Adakron_bay/ImageClassification/Datax.ai/datax-api/future_model/29June_serving_research/tf_serving_example/gan.py:94: softmax_cross_entropy_with_logits (from tensorflow.python.ops.nn_ops) is deprecated and will be removed in a future version.
Instructions for updating:

Future major versions of TensorFlow will allow gradients to flow
into the labels input on backprop by default.

See @{tf.nn.softmax_cross_entropy_with_logits_v2}.

python svnh_semi_supervised_model_saved.py --checkpoint-dir=./checkpoints --output_dir=./gan-export --model-version=2

These are my checkpoint files

Whats wrong in the saving part? help, please.

Hey @gr8Adakron ,

I apologise for a late response. How did you train the model? Which versions of Python and TensorFlow do you have? Such an error occurs if you would rename a tensor between training and exporting the model. BTW my checkpoint files have much smaller size, so I wonder what could be a reason for that.
