调用bokeh时与Tornado相关的错误

Question

我正在运行一个使用bokeh显示交互式绘图的代码。它工作正常，直到我突然发现与龙卷风有关的错误。我安装了最新版本的bokeh和tornado，但它并不能解决问题。回溯很长：

我正在使用为apres数据缩减pyarpes开发的pyarpes代码：

import arpes
from arpes.io import(load_example_data, load_without_dataset, direct_load)
from arpes.utilities import default_dataset
from arpes.utilities.conversion import convert_to_kspace
from arpes.utilities.conversion import *
from arpes.fits import *
from pathlib import Path
import arpes.corrections
import arpes.plotting
from arpes.analysis import *
from arpes.provenance import update_provenance
#DIRECT DATA LOADING test 
p = Path('.')/'arpes'/'example_data'/'test.nxs'
load_without_dataset(p)
f = load_without_dataset(p, location='xxx')
data = f.sel(psi=2, phi=slice(-0.01, 0.07), eV=slice(95.2, 96.5)).transpose('eV', 'phi')  # pocket selection
data_mean = (data - data.mean('eV')) # background substraction
data_mean.S.show()
