I not able to find the test case starting with 'test_sequence_map_' in test_onnx_backend.py. In local setup, currently all cpu tests are passing. Not able to reproduce the failure testcase.

@chinhuang007 Can you please guide me to reproduce this test scenario? Not able to do so using the commands -Install dependencies and ONNX development stage.

@krishnanNuance The test case is from onnx master branch. To reproduce it you need install onnx from source code following https://github.com/onnx/onnx-tensorflow/blob/main/test/backend/test_onnx_backend.py You can update https://github.com/onnx/onnx-tensorflow/blob/main/test/backend/test_onnx_backend.py to exclude new added test case.

Thank you @chudegao . I have excluded the testcase and opened the ticket - #1027 to track the issue.
