我刚刚遇到了同样的问题，显然bokeh< = 0.12.5和tornado = 4.5(请参见

I just experienced the same issue, and apparently, with bokeh <= 0.12.5 and tornado = 4.5 (see https://github.com/dask/distributed/issues/1027)

所以:

• 将您的tornado降级到4.4.3
• bokeh升级到0.12.7(或至少0.12.6 显然是)

• Downgrade your tornado to 4.4.3
• Upgrade bokeh to 0.12.7 (or at least 0.12.6 apparently)

我刚刚升级到bokeh 0.12.7，它的工作原理就像是一种魅力.

I just upgraded to bokeh 0.12.7 and it works like a charm.
