How to display full output in Jupyter, not only last result?
Thanks to Thomas, here is the solution I was looking for:
from IPython.core.interactiveshell import InteractiveShell
InteractiveShell.ast_node_interactivity = "all"

I think you are using the insiders build here is the right setting ,I had the same problem and it worked for me.
"notebook.output.textLineLimit": 500
edit: this will also work for the stable version

The print statement output goes to the stdout
or stderr
on the computer that is running a spark executor.
Considering you have a big cluster having n workers(each storing partition of an RDD or DataFrame). Is is hard to expect the ordered output in a job (for instance map). This may be considered a design choice as well for spark itself. Where will that data be printed out? since nodes are running code in parallel, which of them will be printed first?
So, we dont have interactive print statements inside jobs. These whole thing can also remind you about why we had accumulators
and broadcast
variables.
So, I will advice you to use logs generated by steps instead and work with logs. To view logs in Amazon S3, cluster logging must be enabled (which is the default for new clusters). View Log Files Archived to Amazon S3.
For your second question about sleep()
and print
, python is line buffered, which forces it to wait for a newline before printing to stdout
. If the output is not a console, then even newline won't trigger a flush.
You can force the behaviour as
import time
for i in range(0,10):
print(i,flush=True)
time.sleep(2)
How do you suppress output in Jupyter running IPython?
Add %%capture
as the first line of the cell. eg
%%capture
print('Hello')
MyFunction()
This simply discards the output, but the %%capture
magic can be used to save the output to a variable - consult the docs
IPython Notebook cell multiple outputs
have you tried the display
command?
from IPython.display import display
display(salaries.head())
display(teams.head())
