"ModuleNotFoundError: No module named 'wtforms_json'" when installing Apache Superset - amazon-ec2

I am trying to install Apache Superset on EC2 but I get this error when I run this command:
fabmanager create-admin --app superset
ModuleNotFoundError: No module named 'wtforms_json'
I am following the steps mentioned here:
https://gist.github.com/philippkeller/dedd0ee8221f4b155592149d08a26248

The instructions in the gist you are referencing are not official and/or maintained by the community. They appear to be dated as the proper pypi package is apache-superset (as in pip install apache-superset).

Python Package installed with pip could not be found (Windows)

I have been given two large undocumented C++ and Python projects and I want to understand their structures. For this I would like to create class diagrams with the Python package Sphinx. I opened the command line on Windows 10, installed Python 3.9.6 from the Windows Store and then I typed
pip install sphinx
to install Sphinx globally. When I rerun the command, it tells me that Sphinx is already installed. When I run
sphinx-quickstart
an error is displayed telling me I mistyped the command or that it could not be found. I think Windows does not know the path to Sphinx and I do not know how to fix the problem. I sticked to the official installation guide.

How can I install orion-ml?

The recommended method for installing orion-ml is via pip (e.g., pip install orion-ml) as stated in the github README.md
However, this simple command causes the error

ERROR: Cannot install orion-ml because these package versions have conflicting dependencies.
The conflict is caused by:

mlprimitives 0.2.3 depends on tensorflow<2 and >=1.11.0
mlprimitives 0.2.2 depends on tensorflow<2 and >=1.11.0
To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

This tells us there is a version conflict. How can I resolve this? Thank you
I ran into the same issue and found out that orion-ml only worked with Python >=3.6, <3.8, but I had Python 3.9.2 installed which ended up pullig orion-ml 0.1.0 which is a very old version. I uninstalled 3.9.2 and installed a version under Python 3.8 and it worked
Install Anaconda:
https://www.anaconda.com/products/individual#download-section
Create a virtual environment with python version 3.7.(3.8.8 python makes an error installing "pip install orion-ml")
Run your python 3.7 virtual env.
pip install orion-ml : There's no error install "orion-ml" package.
Create a separate conda environment like:
conda create --name orion python=3.7 # or 3.6
conda activate orion
and then install tensorflow using:
pip install https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-1.8.0-py3-none-any.whl
This will get you rid of the tensroflow error.

RASA pip installation fail: Multiple requirements incompatible

I am trying to install RASA using instructions here
I created a virtual environment and did a pip install rasa. But below is the error message with multiple dependencies incompatible. Do I install all the specified versions from the error message individually?
I found multiple people having installation issues and tried my best to find a solution in the forum, but couldn't.
error message- list of dependencies
It looks like you are trying to install Rasa1.x in an environment where you had previously installed rasa-nlu and rasa-core separately (pre Rasa 1.x). These are old versions that you can't mix with post-1.x Rasa.
I would recommend creating a new virtual environment, making sure it is active, checking that no rasa-nlu or rasa-core is installed, then running pip install -U rasa or pip install -U rasa==<rasa version that you want> if you want a specific version.

zipline installation from Quantopian modifies Anaconda

I am working with Anaconda with python 2.7. In order to do algorithmic trading I wanted to install 'zipline' package using conda giving command as
conda install -c Quantopian Zipline
from Anaconda prompt. After 'Solving environment' message, I got 'Package Plan' which contains packages which will be installed, removed, updated and downgraded. I was astonished to see that it will remove 'anaconda: 5.2.0-py27_3' and downgrade
networkx: 2.1-py27_0 to 1.11-py27_1;
numpy: 1.14.3-py27h911edcf_1 to 1.11.3-py27hc42714f_10;
numpy-base: 1.14.3-py27h917549b_1 to 1.11.3-py27h2753ae9_10;
pandas: 0.23.0-py27h39f3610_0 to 0.22.0-py27hc56fc5f_0.
I canceled the installation.
I have a couple of question here.
Why at all it is necessary for any package installation to remove package 'Anaconda' and downgrade packages like 'numpy', 'pandas' etc.?
Will this action not jeopardize my other python activities?
Shall I go ahead or restrain from installing the packages like this?
Zipline doesn't currently support the latest versions of packages like panda, numpy etc. which causes the messages above.
Well, yes it could make trouble, especially if your other python activities need the latest version of those packages.
Please don't go ahead with the installation like this. I'll explain the best available solution below.
Solution:
Create an environment for Zipline. Let's say (for convenience only) Zipline supports Python 3.5 but you have only installed Python 2.7 on your machine.
So you can create a sandbox-like conda-environment for Python 3.5. It's very straight forward, just use the following commands:
$ conda create -n env_zipline python=3.5
After your isolated environment called env_zipline was created, you have to activated it by using the following command:
$ activate env_zipline
You can install Zipline now by running
(env_zipline)$ conda install -c Quantopian zipline
When you finished your work with zipline you can deactivate the environment for zipline by using the following command:
(env_zipline)$ deactivate
Hope it helps. If your need further information you can check the more detailed documentation of zipline (the steps above are included):

Python 3.5.1 pip install 'ImportError'

While using pip install I am getting the following error:
Error while finding spec for 'pip__main__' <: No module named 'urllib.request'; 'urllib' is not a package>; 'pip' is a package and cannot be directly executed
Any advice on this one?
I thought maybe it was related to the requests module itself but I tried to download other modules and had the same problem.
I've just upgraded from Python 3.3 to v3.5.1 on Windows and hit the same error message. I understand it's not the same as your problem.
It seems that the instructions from the docs to use:
python -m pip install SomePackage
are wrong, at least for Windows because I get the error message quoted by the OP.
I forgot to add the Scripts directory to my path, the same as previous releases. When I add it the problem is fixed. My path now has (for a default install of Python 3.5):
PATH=<blah>;%USERPROFILE%\AppData\Local\Programs\Python\Python35;%USERPROFILE%\AppData\Local\Programs\Python\Python35\Scripts
The pip executable is located in Scripts, so pip commands can now be executed directly, the same as always:
pip install urllib
