triton-cuda-error-fix

triton-cuda-error-fix is a skill for Claude Code, Codex from mindspore-ai/akg. It costs 28 tokens per session (221 once invoked), scanned A, original, Apache-2.0.

A troubleshooting note for a Triton CUDA math-function error. It explains that some functions, such as tanh, must be called through CUDA's libdevice interface.

In plain words
What is it for?
Use it when a Triton CUDA kernel fails because a math function such as tanh is not exposed through tl or tl.math.
Why use it?
It fixes an attribute error caused by calling an unavailable Triton language function directly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

triton-cuda-error-fix scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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))

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
