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

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'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.

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

<!-- 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.

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

add the ibm xlc compiler

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

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?

I think it is not installed . kindly install gensim module.

Integration without coding. Github, DB, cloud services, BI, etc.

When I try to load any of the six basic tutorials, I get the following error:

> Server Error: Refresh your browser and contact us if the problem persists

I have tried and re-tried, so I wanted to submit an issue.

The Idea is to installing mxnet-cu80 (mxnet-cu90, mxnet-cu91 or mxnet-cu92). But the issue is mxnet-80 has dependence with the instalation of libnvrtc8.0 which is installed by the linux console. And there is not possible due to Administrative privileges.

Thank You!
