Question

我正在尝试使用periodic上的DynamicMap函数为路径设置动画，但是我的Jupyter Notebook开始抱怨以下错误消息：

IOPub message rate exceeded.
The notebook server will temporarily stop sending output
to the client in order to avoid crashing it.
To change this limit, set the config variable
`--NotebookApp.iopub_msg_rate_limit`.

Current values:
NotebookApp.iopub_msg_rate_limit=1000.0 (msgs/sec)
NotebookApp.rate_limit_window=3.0 (secs)

这是我的代码：

def paths3():
    N = 50
    x = np.linspace(0,10,N)
    y = (2 * x + 3)

    f = 0.0
    g = 0.5

    while True:
        i = np.clip(int((N-1)*f),0,N-1)
        j = np.clip(int((N-1)*(f-g)),0,N-1)
        if j < 0:
            j = 0

        alpha_max = 1 if f <= 1 else ((1.0-(f-g))*N) / N

        alpha = np.concatenate((np.zeros(j),np.linspace(0.1,alpha_max,(i-j+1)),np.zeros(N-(i+1))))

        data = pd.DataFrame({'x':x,'y':y,'alpha':alpha})

        yield hv.Path(data, vdims='alpha').opts(alpha='alpha')

        if f > 2:
            f = 0
        else:
            f += 0.01

paths3 = paths3()
dmap = hv.DynamicMap(paths3, streams=[Stream.define('Next')()])
dmap

dmap.periodic(0.1, 100)

我看到人们也遇到过类似的问题，但这可以追溯到2017年-带有较旧版本的Jupyter Notebook。

这是Jupyter笔记本中的“关于”部分：

（启动jupyter笔记本时）将消息速率设置为10,000或100,000是否有帮助，就像这样：

jupyter notebook --NotebookApp.iopub_msg_rate_limit=10000

这个SO问题涉及类似的问题：
IOPub data rate exceeded in Jupyter notebook (when viewing image)

HoloViews超出了IOPub消息速率
