1. 1. 1. Description

Summary:
1 test(s) in TestTensorBoardWriter are failing during PyTorch unit test execution on sGPU platform.

Test Class: test/test_tensorboard.py::TestTensorBoardWriter
Number of Failing Tests: 1
Platform: sGPU
Test Type: Unit Test

Version Information:

• PyTorch Commit: 4816fd9
• Test Date: 2025-12-22
• Pipeline ID: 2217097191
• Platform: sGPU

Failure Pattern:
Tests failing with 2 related error patterns - likely common root cause

Error Patterns:
1.

File "/pytorch/test/test_tensorboard.py", line 295, in test_writer

2.

`np.string_` was removed in the NumPy 2.0 release. Use `np.bytes_` instead.

Failing Tests:
1. test_writer

Steps to Reproduce:
1. Pull the PyTorch test image
2. Run the failing test class:

   TEST_CONFIG=cuda python3 test/run_test.py -i test_tensorboard
   

3. Observe test failures

Expected Result:
All tests in TestTensorBoardWriter should pass

Actual Result:
1 test(s) failing with errors shown above
