Hi there,

After clicking JupyterLab link.
Starting Docker Container message is displayed. And then Blank screen is displayed. PSA

Please guide to start JupyterLab and start using Jupyter Notebooks.

Thanks in advance.

Hi,
Since yesterday after running a few commands I am getting 502 bad gateway error again & again and not able to connect to the jupyterLab now. Stuck with my project, please suggest....!!

Just make the basic tool work when you click on it. For three days in a row I get "Application Not Responding"

select FNAME , LNAME
from EMPLOYEES

I'm getting below error:
!conda -- version

/bin/sh: 1: conda: not found

This used to work. What is missing?
Please provide exact fix steps as I'm a real newbie.

IF

1. This service is being paid for


2. Your Jupyter Notebooks service is often down


3. The course is paid for on a monthly basis (Time = Money)

THEN

You should provide the .ipynb files for student to store on their own device to complete lab sessions

ELSE

Respond to user queries/ Get it fixed quick

AND

Refund everyone for the time the service is down/intermittent.

OR

Provide the service at no cost.

is there a timeline to resolve the issue

I follow the knowledge base suggestion to install Ta-lib: !conda install -c quantopian ta-lib --yes

However, I encountered the following error messages.

Solving environment: failed

UnsatisfiableError: The following specifications were found to be in conflict:
- scikit-learn==0.20.1
- ta-lib
- tensorflow==1.8.0
Use "conda info <package>" to see the dependencies for each package.

Can you tell me how to solve this problem?

Thank you

I am not getting connected to Python3 Kernel. It always says reconnecting and finally will be dead. Please suggest

<!-- Your answer is below:
a = np.array([-1, 1])
b = np.array([1, 1])
Plotvec2(a, b)
print("The dot product is", np.dot(a,b))
-->

This code is giving error.

Error: Plotvec2 is not defined.

Dear help desk,

I am facing alot of issues while working on jupyter notebooks, after running a few commands the ui is stuck which forces the user to referesh the screen and the same thing happens after executing a few commands.

This issue applies to R Studio, Zeeplin notebooks as well

I'm trying to access the Jupyter Notebook and I'm getting the following message: "500 Internal Server Error ". What should I do?

add the ibm xlc compiler

Running the GPU applications clock at 875 MHZ instead of 562 MHZ

I am getting error 502 Bad Gateway since yesterday while connecting to Jupyter for IBM PowerAI.

Is there some kind of maintenance or issue going on?

Because if it is permanent or if it will take a lot of time I would atleast like to retrieve some of the files that I was working on so that I can resume elsewhere

It stays forever on loading. Already tried incognito and eliminated cookies but with no sucess. Tried to contact support "Contact support" is unclickable

Hey, does anyone knows if the workbench is undergoing any maintenance or something else? I used the Jupyter Notebooks just a few hours ago and it was good. But just now, I can't log into the workbench, there's always a 502 error. Is this a temporary issue or other things are happening?
Thanks.

Sometimes we have to have long-running tasks! How does idling work for jupyter lab? Can I close the browser tab or suspend my local client while the kernel continues running on your side?

If I connect from two different computers, do I use two different kernels, or can I continue from the same kernel?
