CopyIt clearly inspired Uvicorn and Starlette, that are currently faster than Sanic in open benchmarks.
That's why **FastAPI** is based on Starlette, as it is the fastest framework available (tested by third-party benchmarks).
Sanic makes use of ``uvloop`` and ``ujson`` to help with performance. If you do not want to use those packages, simply add an environmental variable ``SANIC_NO_UVLOOP=true`` or ``SANIC_NO_UJSON=true`` at install time.
$ export SANIC_NO_UVLOOP=true
$ from sanic import Sanic
from sanic.response import json
app = Sanic("my-hello-world-app")
@app.route('/')
async def test(request):
return json({'hello': 'world'})
if __name__ == '__main__':
app.run()

Starting in v22.3, --debug will no longer automatically run the auto-reloader.
Switch to --dev to continue using that functionality.

QUESTION
I want to use Motor with Sanic but I came across the following text in the documentation:
Threading and forking
Multithreading and forking are not supported; Motor is intended to be used in a single-threaded Tornado application. See Tornado’s documentation on running Tornado in production to take advantage of multiple cores.
Does this mean Motor cannot be used with multiple Sanic workers? Has anybody attempted that?
...ANSWER
Answered 2021-May-20 at 13:00Sanic is not multi-threaded. And, forking is only used to setup the workers. If you instantiate motor using one of the server life cycle listeners, you will have no problem.

i have been using rasa for the past few weeks without problems. But recently i had issues with the installation of Spacy, leading me to uninstall an reinstall python. The issue may have occurred because of some dualities between python3.8 and 3.9 which i wasnt abled to pinpoint.
After deleting all python version from my computer, i just reinstalled python 3.9.2. and reinstall rasa with:
...ANSWER
Answered 2021-Mar-21 at 14:59rasa 2.4 declares compatibility with Python 3.6, 3.7 and 3.8 but not 3.9 so pip is trying to find one compatible with 3.9 or at least one that doesn't declare any restriction. It finds such release at version 0.0.5.
To use rasa 2.4 downgrade to Python 3.8.
PS. Don't hurry up to upgrade to the latest Python — 3rd-party packages are usually not so fast. Currently Python 3.7 and 3.8 are the best.

QUESTION
I'm attempting to redirect all requests in sanic web server. So, for example, if someone went to localhost:5595/example/hi it would forward to a website. I know how to normally do that in sanic, but it would be to slow to redirect 100 urls. Is there any faster way of doing this?
ANSWER
Answered 2021-Feb-23 at 07:25I am not 100% sure if this is the answer you are looking for. But, if you are asking about making a super crude proxy server in Sanic to redirect all requests, something like this would do (see server1.py).
QUESTION
I'm trying to integrate GraphQL to my web service which was written in tornado (python). By using dataloaders, I can speed up my request and avoid sending multiple queries to my database. But the problem is I can't find any examples or the definition that equal the "context" variable at request level to store the GraphQLView. I found an example written in sanic refer to this link. Are there any definition in "tornado" that equal to "context" (get_context) in sanic ??? Or any examples to resolve the attributes like that:

QUESTION
I have exactly the same problem as mentioned in PIP install rasa-x takes forever. In the Rasa installation guide they say, you have to create an environment first. Everytime I do: conda create --name rasa python==3.7.6 it automatically downloads pip-20.3.3. If I now try the pip install --upgrade pip==20.2 command it shows the following error: Error. What did I do wrong? Thanks for the help!
**Update: python -m pip install --upgrade pip==20.2 worked, but now there is another problem when trying to install Rasa-X:Rasa-X installation error
here is the code
...ANSWER
Answered 2021-Jan-25 at 13:34I had this issue as well and for me installing pip packages with python -m pip install worked. So python -m pip install --upgrade pip==20.2 should work for you.

QUESTION
When creating a new rasa assistant with rasa init I get the interface below. What command can I run from the command line to get back to this interface after I exit? Sometimes I'd rather just use the cmd interface rather than running rasa x and using the browser.
ANSWER
Answered 2020-Nov-04 at 03:37So after running rasa init, now you have your project ready, and model has been trained. To get this interface back, in command Line interface your have to run rasa shell which will load trained model and lets you talk to your assistant on the command line.

Install sanic
You can use sanic like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
