Trying to convert weights to TensorRT Graph tensorflow version issue

Installed packages:

GTX 1070 8Gb memory, Ryzen 5, Ubuntu 20.04

When I try to convert the model weights to TensorRT engines I get the following error:

  File "/home/dt/miniconda3/envs/TensorRT/lib/python3.6/site-packages/tensorflow/python/framework/importer.py", line 497, in _import_graph_def_internal
    graph._c_graph, serialized, options)  # pylint: disable=protected-access
tensorflow.python.framework.errors_impl.InvalidArgumentError: NodeDef mentions attr 'validate_shape' not in Op<name=AssignVariableOp; signature=resource:resource, value:dtype -> ; attr=dtype:type; is_stateful=true>; NodeDef: {{node AssignNewValue}}. (Check whether your GraphDef-interpreting binary is up to date with your GraphDef-generating binary.).

During handling of the above exception, another exception occurred:

What tensorflow version was used to save these weights? I am using the same requirements.txt for my environment but still running into this issue.
