我想统计特定 URL 路径中的请求数。

app = FastAPI()
counter = 0

@app.get("/do_something")
async def do_something():
    global counter
    counter += 1
    return {"message": "Hello World"}

这段代码可以吗？计数器应该是线程安全的？阿辛西奥安全吗？这是计算请求的正确方法（没有数据库）吗？在这种情况下，“do_something”函数中的“async”有含义吗？以及如何让它与多个工人一起工作？

Clipnorm 和 Clipval 之间有什么区别？

前任：opt = SGD(lr=0.01, momentum=0.9, clipnorm=1.0)

我无法使用 rbenv 安装任何 ruby​​ 版本。我尝试了 2.6.10 2.7.7 或 3.2.0 。

这是我执行时遇到的错误：
