TypeError: Expected int32 passed to parameter 'n' of op 'QueueDequeueManyV2', got 1.0 of type 'float' instead.

Prerequisites

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

• I am using the latest TensorFlow Model Garden release and TensorFlow 2.
• I am reporting the issue to the correct repository. (Model Garden official or research directory)
• I checked to make sure that this issue has not already been filed.

1. The entire URL of the file you are using

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

2. Describe the bug

I got the following error when running bash train.sh.
The README doesn't tell us which TF to use. See also #8877

Expected int32, got 1.0 of type 'float' instead.

3. Steps to reproduce

bash train.sh

4. Expected behavior

The program runs normally without raising TypeError: Expected int32 passed to parameter 'n' of op 'QueueDequeueManyV2', got 1.0 of type 'float' instead.'.

5. Additional context

None
