I am using JupyterDash, recently I updated dash, then the run stuck at running server and it never finish when running the below code. I am using jupyter lab. Not sure why? so I have restart kernel each time and the issue is gone. Thanks
if __name__ == "__main__":
app.run_server(mode='external',debug=True,port=8060)

I've been facing an intermittent issue with pandas profiling widget not rendering & it has been going on and off for awhile.
I've tried this in the command prompt:
jupyter nbextension enable --py widgetsnbextension
it comes up with " - Validating: ok" but still not rendering.
A quick google search led me to a few githubs/pandas-profiling/issues sections but they were a few years old.
I had this problem in Kaggle, I think it is related to memory. It happens when I repeat running my notebook a few times, without restarting the kernel.
To fix it, I just clicked Run, then Restart and Clear Outputs, and it's working again.
I have since then optimized my codes to release memory when done with them, as well as get into the habit of restarting and clearing outputs before a fresh run.
It hasn't happened on my local environment with Jupyter Notebook, probably because I have better memory locally. But if it did happen, I guess I would select Kernel, then Restart and Clear Output.

Problems getting pygame to show anything but a blank screen on Macos
(10 answers)
Closed 2 years ago.
Just started programming in python and pygames.
Whenever I try running a py file with pygames, the pygames window will appear, but there will be absolutely nothing in it. No errors in the log, but nothing shows, it's just a gray screen.
I tried running it on IDLE, and through the command line (I'm on a mac so I use the terminal)
And it's not just my programs that aren't showing anything, I've tried to run one of pygames examples, and it will still not display anything. For example, if I run the pygames alien example, the window will appear with a blank gray background. I'll hear the audio for the program, but no display.
Anything would help, I'm at a loss especially since no errors are showing in the log.
EDIT1:
I'm using Python 3 (and I really need to keep using Python 3)
EDIT2:
I'm using python 3.7. pygames version 1.9.4. The examples are with the pygames, they were downloaded together, so I assume it's for that version.
EDIT3:
ok, my OS is Mojave 10.14. I've tried starting the application by: opening the file, running it on IDLE, and running it through the command line, none have worked. python2 is installed, but when I run the pygame it's a python3 file
Known issue with Mojave - see their issue tracking: https://github.com/pygame/pygame/issues/555
You can also install new pygame using pip install pygame=2.0.0.dev6. This
worked in my case.
I'm trying to deploy my own .bna file to a business network using
this tutorial.
The only difference is that I am doing this with three organizations.
Everything works fine until I run the step eight because when I run this command:
composer network ping -c alice#trade-network
I got this error:
Error trying to ping. Unexpected end of JSON input.
Does anybody know how can I solve this?
Thank you
I had the same issue, and I knew it was a matter of local configuration since it stopped working suddenly after throwing several commands. So, I fixed it by stopping fabric and tearing it down.
Then, started fabric, created my peer credential and deployed everything again.
Review the commands in here (section: Controlling your dev environment):

We were trying to add some selenium scripts on Jenkins but whenever we gave the command I was receiving an error "Chromedriver.exe has stopped working".
I moved chromedriver to another location, such as C:, to test it and I found that if I manually doubleclick it from the folder is working fine. But whenever I try to start it from the command prompt is giving me the error "Chromedriver.exe has stopped working".
Any ideas?
Environment: Windows 10 64bit
I have experienced the same issue. In my case it was explicit .quit() missing. This was only case with 32-bit Python, 64-bit Python was working fine even without it.
browser = webdriver.Chrome()
browser.get(url)
#do some work with the downloaded contents
browser.quit()
Some time ago, I've deployed a YouTrack5 instance on OpenShift, using this excellent tutorial. It works fine and smoothly.
Now, I want to install YouTrack6. Unfortunately, the same method can't be used for it, as since version 6 YouTrack .war file is no longer available.
So, I've tried to deploy YouTrack6 jar via a DIY cart, which should be ok, as the jar can be run standalone.
This is the command line that I've provided in the
.openshift/action_hooks/start script:
nohup /usr/lib/jvm/java-1.7.0/bin/java -Xmx1g -XX:MaxPermSize=250m -Djetty.home=$OPENSHIFT_DATA_DIR -Duser.home=$OPENSHIFT_DATA_DIR -Ddatabase.location=${OPENSHIFT_DATA_DIR}teamsysdata -Djava.awt.headless=true -jar ${OPENSHIFT_REPO_DIR}youtrack-6.0.12463.jar ${OPENSHIFT_DIY_IP}:${OPENSHIFT_DIY_PORT} &
Indeed, it works, the application is deployed and started - BUT: it is very unstable, looks like it crashes and caused to restart after just every few actions.
From the logs, I couldn't understand where the problem lies, looks like on YouTrack's side everything's ok.
My question is - what can be the problem that causes this unstable behavior, and is there any way to work around it (maybe by changing the command line flags, etc.)?
