I followed this notebook to try bokeh with iPyhton Notebook: https://github.com/bokeh/bokeh/blob/0.12.3/examples/howto/notebook_comms/Basic%20Usage.ipynb
I dont know how to interpret and fix those errors:

bokeh : 0.12.3
tornado: 4.4.2
python: 2.7
the problem was that the iPython notebook kernel was out of sync. restarting the notebook server was the solution

I had the following error, for example, when running the first cell in pose.ipynb. I have tried reinstalling drake and manipulation on my local machine with the newest version, but I still have the same problem. Can you please help me out with it?

I am running pyspark from an Azure Machine Learning notebook. I am trying to move a file using the dbutil module.
from pyspark.sql import SparkSession
spark = SparkSession.builder.getOrCreate()
def get_dbutils(spark):
try:
from pyspark.dbutils import DBUtils
dbutils = DBUtils(spark)
except ImportError:
import IPython
dbutils = IPython.get_ipython().user_ns["dbutils"]
return dbutils
dbutils = get_dbutils(spark)
dbutils.fs.cp("file:source", "dbfs:destination")
I got this error:
ModuleNotFoundError: No module named 'pyspark.dbutils'
Is there a workaround for this?
Here is the error in another Azure Machine Learning notebook:
---------------------------------------------------------------------------

I have strange issue, the following code works on one solution file in the same working directory.
But when I copy call the exact same code to my sheet. I get this error, so I have no idea to fix this.
Here's the code:
import matplotlib.pyplot as plt
import numpy as np
%matplotlib inline
x = np.zeros(20)
x[:5] = 10
x[5:15] = np.arange(12,31,2)
x[15:] = 30
plt.plot(x)
plt.plot([4,4],[8,32],'k--')
plt.plot([14,14],[8,32],'k--')
plt.ylim(8,32)
Traceback (most recent call last)<ipython-input-65-6b573104eb1d> in <module>()

I literally copy and pasted the example of how to use the hover tool from bokeh's documentation and I still can't get this damn thing to work. I just want bokeh's hover tool to display the x and y coordinates. I think I've implemented it correctly but let me know if anything's wrong. (The ASCII file reads in flawlessly and the graph plots correctly and all the other tools work)
