problem with "tensorflow.python.framework.errors_impl.OutOfRangeError"

[512792354]

Describe the bug
HI, I encounter a bug when testing with command "ae_train exp_group/my_mpencoder ", and it always comes out with the same output like this:
"tensorflow.python.framework.errors_impl.OutOfRangeError: 2 root error(s) found. (0) Out of range: End of sequence".
I use 8000 jpg images with resolution of 720*540. Also use 3D model in .ply format and convert it into ASCII format with MeshLab software. The model has color. But it finally gets the same problem. Could you help me with that? I attack the whole dialog below. The environment information is also attached.
The terminal information:
jhl@jhl:~/AugmentedAutoencoder_multipath/a_project$ ae_train exp_group/my_mpencoder -d

WARNING:tensorflow:From /home/jhl/.local/lib/python3.7/site-packages/auto_pose/ae/multi_queue.py:128: DatasetV1.make_initializable_iterator (from tensorflow.python.data.ops.dataset_ops) is deprecated and will be removed in a future version.
Instructions for updating:
This is a deprecated API that should only be used in TF 1 graph mode and legacy TF 2 graph mode available through tf.compat.v1. In all other situations -- namely, eager mode and inside tf.function -- you can consume dataset elements using for elem in dataset: ... or by explicitly creating iterator via iterator = iter(dataset) and fetching its elements via values = next(iterator). Furthermore, this API is not available in TF 2. During the transition from TF 1 to TF 2 you can use tf.compat.v1.data.make_initializable_iterator(dataset) to create a TF 1 graph mode style iterator for a dataset created through TF 2 APIs. Note that this should be a transient state of your code base as there are in general no guarantees about the interoperability of TF 1 and TF 2 code.
