Instructions Doesn't Work for Freezing Nasnet and PNasNet

Prerequisites

Please answer the following question for yourself before submitting an issue.

• [x ] I checked to make sure that this issue has not been filed already.

1. The entire URL of the documentation with the issue

https://github.com/tensorflow/models/tree/master/research/slim

2. Describe the issue

The description provided to freeze the models works only with ".ckpt" files. The checkpoints provided for NasNet and PNasNet models doesn't work with the "freeze_graph". Here is the command I used and the output:

Command:

freeze_graph \
    --input_graph=nasnet_large.pb \
    --input_checkpoint=model.ckpt.data-00000-of-00001 \                                                                                                                                                                                                              
    --input_binary=true --output_graph=nasnet_large.pb \
    --output_node_names=Merge_1/MergeSummary

Error:
