数学函数调用错误

  • 报错特征: AttributeError: module 'triton.language' has no attribute 'tanh'
  • 修复:
    • Triton CUDA 后端的数学函数需通过 tl.extra.cuda.libdevice 模块调用
    • 避免直接使用 tl.math.xxxtl.xxx
# 错误:直接使用 tl.tanh
result = 0.5 * x * (1.0 + tl.tanh(inner))

# 正确:通过 libdevice 调用
result = 0.5 * x * (1.0 + tl.extra.cuda.libdevice.tanh(inner))
