Describe the problem

I use the following command to freeze a ckpt file to pb file:

    freeze_graph(
        input_saver=None,
        input_graph=pbTxt,
        input_binary=False,
        clear_devices=True,
        output_graph=pbPath,
        restore_op_name=None,
        initializer_nodes="",
        input_meta_graph=None,
        filename_tensor_name=None,
        input_saved_model_dir=None,
        output_node_names=outputOp,
        variable_names_blacklist='',
        input_checkpoint=iCheckpoint,
    )

In tf-1.8.0 everything seems well, however in tf-1.10.1, I meet the following error:

  File "/usr/local/lib/python2.7/dist-packages/tensorflow/python/tools/freeze_graph.py", line 254, in freeze_graph
    checkpoint_version=checkpoint_version)

    for converted_saveable_object in self.SaveableObjectsForOp(op, name):

    variable, "", name)

    self.handle_op = var.op.inputs[0]
  File "/usr/local/lib/python2.7/dist-packages/tensorflow/python/framework/ops.py", line 2001, in __getitem__
    return self._inputs[i]
IndexError: list index out of range

I wonder why the tf-1.10 is not tested before release ???

If I use tensorflow 1.10 version freeze graph.py, it comes with
ImportError: cannot import name 'checkpoint_management' tf1.10

If I use working version such as tensorflow 1.8, message comes below

Tensorflow is hard to use with so many bugs, I wonder why not fixing bugs before developing new functionality.

And the issue block on github is useless, since no useful answers are provided. I wonder maybe turn to using pytorch would be better.
