Now when I run the command locust --help
I get this on the command line
'locust' is not recognized as an internal or external command,
operable program or batch file
What could be the issue?Any help would be appreciated.


It seems that you have not added python 3.7 in the environment variable PATH. While this could have been achieved while installing python itself by checking the box to Add Python to the path. However, you can still add the location of Python37(where python37 is installed) by going to This PC--Right-Click->Properties-->Advanced System Settings-->Environment Variables tab-->System Variables--Edit Path & add value*.
I recently wrote steps for setting up locust on windows which might help -https://www.qamilestone.com/post/set-up-locust-on-windows

I guess you erroneously added : at the end of last command. From the documentation:

python -m mitoinstaller install
However, I had some errors after python -m pip install mitoinstaller due to missing dependencies:

Building wheels for collected packages: grpcio
Running setup.py bdist_wheel for grpcio ... /
After this, a wired thing happen my ssh stop responding until I restart the AWS EC2
My Environment
Python version = 3.6.9
pip verions = 9.0.1
Ubuntu version = 8.04.5 LTS (Bionic Beaver)
Note: I also have REST API use Nginx reverse proxy a Node server via pm2

By following #jordanm's path I found that pip install is building some wheels (which is a heavy task and need more memory and resources)
Solution
Change your instance type to higher tier's (temporary) [Select the instance > right click > change instance type > choose whatever you want, I go with t3.xlarge]
SSH into your machine
Run the pip install commend, (If it crashes or frizzy again just repeat step 1 with higher tier instance type)
When the commend is successfully executed change back to your instance type. (if you want t to)

It's building the wheels. First time it does that will take ages, especially on a small instance.

Consider using the `--user` option or check the permissions.
Can anybody tell me the solution of this?

pip uninstall python 3.8.4
This command will never work. pip is a python package manager, i.e. for an installation of python, pip is responsible to install modules to that python installation. It does not manage the installation of python itself
To your error with the tensorflow installation:
pip install tensorflow
and
ERROR: Could not install packages due to an EnvironmentError: [WinError 5] Access is denied: 'c:\\programdata\\anaconda3\\lib\\site-packages\\wrapt-1.11.2.dist-info\\INSTALLER'
This is caused by the fact that the c:\\programdata is write protected from non-admin users, so in order for your command to succeed, you should run your cmd as admin.
BUT:
It seems like you have installed anaconda and are trying to install tensorflow into the base environment using pip. Pip in turn tries to uninstall some already existing package, probably to fulfill the tensorflow requirements. But the already existing package are probably installed by conda when you first installed anaconda, so you ware getting into dangerous waters here and you are risking to break your base environment, so two suggestions:
Create a new environment conda create -n tf tensorflow-gpu
Use conda commands to install tensorflow. conda install tensorflow-gpu will give you tensorflow
To your other question:
How to downgrade python
The solution is also to use a conda command:
conda install python=<some version>
or, even better, simply create an environment with the version you need:
conda create -n py37 python=3.7
would for example give you an environment called py37 with python3.7 installed. It can be activated and used with
conda activate py37

I'm using Python 3.7.4
.........................................................................................................

Install pyqt5:
pip install pyqt5
Install spyder:
pip install spyder
If that doesn't work, try using pip3.

I ended up uninstalling the entire Python directory and installing Python 3.9 instead. Now I can install Spyder again.

Why did a new version of a library get installed when the current one satisfied setup.py requirements?

I developed a package that uses matplotlib and so I've added the following line to my project's setup.py: (link to setup.py)
install_requires=[
'matplotlib>=2.0.0',
...other libs
]
However, when I tried to install my package into a virtualenv (via pip install) that already had matplolib version 2.1.0 installed, pip fetched and installed matplotlib version 3 regardless.
Is this expected behaviour or was there something else happening here?

Let's me try with a new empty virtualenv:

See? matplotlib is not upgraded. Requirement already satisfied: matplotlib>=2.0.0. Can you show similar output of your terminal so we better understand what is going on?

Since you are specifying version to be >=2.0.0 (greater than 2.x.x), pip is installing latest version 3.x.x.
If you want to install version 2.0.0 then try using following code:
install_requires=[
'matplotlib==2.0.0'
]
