Models: Eval.sh crashes for /models/research/feelvos/

[nirat1606]

System information

• What is the top-level directory of the model you are using: /models/research/feelvos/
• Have I written custom code (as opposed to using a stock example script provided in TensorFlow): trying to run /models/research/feelvos/ eval.sh
• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Red Hat Enterprise Linux Server release 7.7 (Maipo)
• TensorFlow installed from (source or binary): source ,TensorFlow-gpu using pip (python 2.7), installed in a conda image
• TensorFlow version (use command below): 1.14.0
• Bazel version (if compiling from source): N/A
• CUDA/cuDNN version: no gpu acceleration used (although Cuda 9.2)
• GPU model and memory: no gpu acceleration used
• Exact command to reproduce: from the folder /models/research/feelvos/ , run the file ./eval.sh

Describe the problem

Followed the exact instructions to setup /models/research/feelvos/.

While running the code, specifically deeplab setup gives the warning:

WARNING:tensorflow:Entity > could not be transformed and will be executed as-is. Please report this to the AutgoGraph team. When filing the bug, set the verbosity to 10 (on Linux, export AUTOGRAPH_VERBOSITY=10) and attach the full output. Cause: converting >: AssertionError: Bad argument number for Name: 3, expecting 4

It gives error in /models/research/feelvos/ vis_video.py. If I debug, at line
Res = session.run(ops)

Source code / logs
And then the code crashes giving the error:

I tried using gast 0.2.2 and that resolved the error. Also check your dataset folder tfrecord for val: if it's empty then try re-converting the data.
