I could not find any solution in google for this.
After a glimpse at the error Message,
You seem not to have access to /opt/root/6.26.10-install/etc/notebook/migrated
How did you install the anaconda? (globally or on root?)
since you are currently running as user "souvik"
Try running:
sudo jupyter-notebook --allow-root
Then post back the results.
In case the above command started jupypter-notebook successfully,
we can change the ownership of /opt/root/6.26.10-install/etc/notebook/from rootto you (souvik) using chown.

Django app dependencies on Shared hosting(Cpanel)

I've been trying to deploy an Django app in a Shared hosting with Cpanel.
But every time that I tried to install google-cloud-automl dependency I get this message on the server
Complete output from command python setup.py egg_info:

Any idea how I may install this dependency?
It was the pip version used on my virtualenv so after updated it worked

I am very new to spyder and I have absolutely no idea how to solve this.
I have already tried to uninstall anaconda and install it again but the same error keeps appearing...
Does anyone have any idea how I could solve this?

Kernel error in spyder and jupyter notebook

I tried to use the Anaconda Navigator, but I'm getting this kernel error.
I had previously installed python 3.8 without Anaconda and had installed jupyter in it using pip, then I uninstalled it and installed Anaconda again.
Since then this error arises whenever I try to compile a file and even in the jupyter notebook.
I tried :
1.) Reinstalling Anaconda
2.) Updating the setup tools
None of these worked.

Issue resolved.
The problem:
I had previously installed jupyter using pip install, when I was working on python 3.8.
Now, I uninstalled python 3.8 and installed Anaconda instead. This again reinstalled jupyter, thus was the cause of the problem.
To resolve this, I uninstalled jupyter from AnacondaPrompt using conda uninstall jupyter , and then reinstalled it, this time from conda install jupyter.
This resolved the kernel error.
This is permission issue for that particular folder
Set the environment path variables C:\Users\DELL\AppData\Roaming\jupyter\runtime
give the permission and it will work

What do I need to do?
It can also be done without executing pip as superuser (which you should, at least, try not to):
Create the directory:
sudo mkdir /usr/local/selenium
Give yourself ownership of the directory:
chown your_username /usr/local/selenium
Install Selenium:
pip3 install -U selenium
Did you try to run pip install as a super user? It's common to have PermissionError when you miss the sudo. If you didn't, try sudo pip3 install -U selenium.
