how to upgrade Apache Superset 1.4.1 to the latest (2.0),i want to use the version 2.0.how to migrate database,update database etc?
You need to run the following to upgrade
pip install apache-superset --upgrade
However, you may face some dependency problems,as mentioned in this issue. This is about the wrong dependencies being fetched.
To sort it out, use the following (from the issue itself)
pip install Werkzeug==2.0.3
pip install flask==2.0.3
pip install jinja2==3.0.1
Then run the superset database upgrade

The Jupyter docs recommend using conda to install jupyter, if the runtime python is version 3.5 or lower. Installation is pretty straightforward with conda.
Follow Anaconda’s instructions for downloading and installing the Python 3.5 version.
$ conda install jupyter
$ pip list | grep ipython
ipython 7.29.0
ipython-genutils 0.2.0
$ ipython notebook --ip=0.0.0.0
This question is to discover if it's possible to install a 3.5 compatible jupyter using only pip, and without conda.
Given the following environment:
$ python --version
Python 3.5.2
$ sudo apt-get install python3-pip
$ pip3 --version
pip 8.1.1 from /usr/lib/python3/dist-packages (python 3.5)
Installing ipython is possible with the following restrictions:
$ python3 -m pip install ipython==7.9 traitlets==4.3.3 jedi==0.17.2
Jupyter, however, doesn't install gracefully.
The following allows for installation:
pip3 install jupyter ipython==7.9 traitlets==4.3.3 jedi==0.17.2 pyzmq==20 argon2-cffi==21.1.0
But at runtime, jupyter crashes:
File "/home/vagrant/.local/lib/python3.5/site-packages/ipython_genutils/importstring.py", line 31, in import_item
module = __import__(package, fromlist=[obj])
File "/home/vagrant/.local/lib/python3.5/site-packages/notebook/__init__.py", line 27, in <module>
from .nbextensions import install_nbextension
File "/home/vagrant/.local/lib/python3.5/site-packages/notebook/nbextensions.py", line 15, in <module>
from jupyter_core.paths import (
File "/home/vagrant/.local/lib/python3.5/site-packages/jupyter_core/__init__.py", line 1, in <module>
from .version import version_info, __version__
File "/home/vagrant/.local/lib/python3.5/site-packages/jupyter_core/version.py", line 21
_suffix_ = f'.dev{version_info.serial}'
Is it possible to install a 3.5 friendly jupyter using pip?

I would like to upgrade from "networkx 2.4" to "networkx 2.2". How to do this using python's pip command? Thank you
You can force a specific version with the == operator. pip should automatically uninstall the current version you have installed and install the older version:
pip install networkx==2.2
If I try to install pykml with conda I got the following conflict:
Specifications:
pykml -> python[version='2.7.|3.4.|3.5.|3.6.|<3']
Your python: python=3.7
My question is now if there exist a way to install pykml in python3.7 and to avoid downgrading my version of python?

Problem resolved after rebooting the machine. Not sure why this worked, other than I'd installed a lot of packages to get to this stage, and maybe something required a restart to complete the installation? If anyone can explain the problem, I'd be interested to understand why that might be?
