@formers #4372 分析CI 报错原因

@github-actions

这个后台任务的输出文件已经被清理了,但我之前通过 TaskOutput 工具已经获取并分析了完整的 CI 日志内容。


补充信息:测试重试情况

从日志中可以看到:

=================================== following tests were retried ========================
test_tokenizer_encode_decode failed on attempt 1! Retrying!
    AssertionError: 0 not greater than 0

test_tokenizer_encode_decode passed on attempt 2!

test_tokenizer_with_model failed on attempt 1! Retrying!
    ValueError: Broadcast dimension mismatch...

test_tokenizer_with_model passed on attempt 2!

关键发现

  1. 首次运行失败:由于 aistudio 资源不可用
  2. 重试后通过:说明测试本身是正确的,只是遇到临时性资源问题
  3. 最终结果2646 passed, 183 skipped, 15 warnings, 2 errors, 2 retried

最终结论

尽管测试在重试后通过了,但由于存在错误(2 errors),CI 仍然返回失败状态码 1。建议:

  1. 短期修复:添加空序列保护代码,避免因外部资源问题导致模型崩溃
  2. 长期优化:使用更稳定的 tokenizer 或 mock 测试依赖

完美!现在我已经找到了所有的错误信息。让我生成分析报告:

日志分析报告

根据对 PR #4372 的 CI 日志分析,发现以下问题:


流水线名称:unittest-gpu-ci

问题标签:单测存在 Bug

修复建议:

以下单测存在 Bug,需要修复:

1. tests/transformers/openelm/test_modeling.py::TestOpenELMToken::test_tokenizer_encode_decode

  • 错误现象AssertionError: 0 not greater than 0
  • 问题分析:tokenizer.encode() 返回空列表,说明 tokenizer 无法正确编码文本
  • 根本原因:从日志中看到多个 <Response [404]> 错误,tokenizer 所需文件(tokenizer.json, added_tokens.json, special_tokens_map.json等)下载失败
  • 修复建议
    1. 检查 tokenizer 模型路径 _TOKENIZER_ID (hf-internal-testing/llama-tokenizer) 是否正确
    2. 确保 tokenizer 所需文件能正常下载或已预置在测试环境
    3. 可能需要更换为可用的 tokenizer 源或使用本地预下载的 tokenizer

2. tests/transformers/openelm/test_modeling.py::TestOpenELMToken::test_tokenizer_with_model

  • 错误现象
    ValueError: (InvalidArgument) Broadcast dimension mismatch. 
    Operands could not be broadcast together with the shape of X = [1, 4, 0, 0] 
    and the shape of Y = [1, 128, 0, 0]. 
    Received [4] in X is not equal to [128] in Y at i:1.
    
  • 问题位置paddleformers/transformers/openelm/modeling.py:339
    attn_weights = attn_weights + causal_mask
  • 问题分析
    • attention weights 的 shape 是 [1, 4, 0, 0](q_h=4)
    • causal_mask 的 shape 是 [1, 128, 0, 0](可能是max_heads=128)
    • 序列长度维度为 0,说明 input_ids 也是空的(与第一个错误相关)
    • 即使 input_ids 不为空,head 数量维度不匹配(4 vs 128)
  • 修复建议
    1. 首先修复 tokenizer 问题,确保 input_ids 不为空
    2. 检查 causal_mask 生成逻辑,确保其 head 维度与当前层的 q_h 一致,而不是使用全局的 max_heads
    3. 查看 OpenELM 模型中 causal_mask 的生成代码,可能需要根据每层的实际 head 数量动态调整

总结

两个错误都与 OpenELM 模型的新增代码有关。核心问题是:

  1. Tokenizer 文件下载失败导致无法编码文本
  2. Attention mask 维度与模型实际的 head 数量不匹配

建议优先修复 tokenizer 问题,然后再检查模型 attention 逻辑中的维度计算。
