QUESTION
ANSWER
Answered 2022-Feb-03 at 12:54In order to make a package importable, it must have an (optionally empty) __init__.py file in its root. So first create an empty __init__.py file in the Utils directory.
Furthermore, you don't have to alter the import path, since you start the Flask app from the Clean_code, the simple relative importing will work. So the first three line can be removed from main.py.
QUESTION
I'm trying to put a dictionary into a .txt file, and then using json.load(File.read()) parse the string to a dictionary.
For some reason it is not working.
CODE:
...ANSWER
Answered 2021-Aug-20 at 13:57Since I don't have reputation to comment I'm writing this as an answer. I tried to run your erroring code on my machine and it had no problems with it whatsoever (provided I replace path with something like 'check_json.json'). This tells me that it's related to your environment.
The error itself (json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)) seems to pop up when you're operating on an empty string, meaning that File.read() is returning an empty string that json.loads doesn't know what to do with.
Some possible issues could be:
- You've redefined a reserved keyword somewhere and so Python is struggling to get the objects to behave as they should (a shot in the dark based on your use of File and Dictionary. Yes they're not builtins/reserved words but who knows what the rest of the code looks like right?)
- Something's wrong in your Python install and you need to reinstall it.
- You have some sort of strange permissions that stop you from actually saving down data to this file that you're creating.
QUESTION
I try to find a way to create an user counter with Prometheus and Grafana for my Flak app..
The Flask app run as wsgi with multiple workers and is also scaled via ngninx (docker scale). Because of this I create a counter with different labels. Where the labels is the hostname of the docker container.
The challenge that I now have is how to combine all of those counters into a single graph in Grafana.
In this example I have two processes with one having 5 and the other having 2 invokes. Instead of having to two graphs I would like to see only one with having a final value of 7.
I tried to use sum for all values but that did not give me the desired graph.
Also tried sum_over_time with sum but values are also not correct.
Using a sum without does also not solve it for me.
...ANSWER
Answered 2021-Nov-29 at 16:25You have to use sum by / without.
withoutremoves the listed labels from the result vector, while all other labels are preserved in the output.
bydoes the opposite and drops labels that are not listed in the by clause, even if their label values are identical between all elements of the vector.
For your specific problem, it should be something like this :
QUESTION
I have a Flaks API with some endpoints. I use multiprocessing to run it parallel to my Program. Tkinter is started with window.mainloop().
I split all of them into their own classes (I don't know if this affects smth).
I now want to change the text of a label on my tkinter Label. I am using mylabel.config(text="myText") and want to call this from my API Endpoint (A function like this:)
ANSWER
Answered 2021-Nov-12 at 21:42After more and more research I finally found an Answer. To access another Process (here the main Process) from another one (here my Flask API) you need to use a Queue or Pipe (Queue Documentation).
This Queue (or Pipe) allows you to communicate with another Process. One reads from the Queue (here my Tkinter Window) and one (or more) write into it. Maybe this helps someone else with the same Problem.
Thanks for your help :)

I want to import mongoengine in a python file which requires sudo to execute but I am getting the following error ModuleNotFoundError: No module named 'mongoengine'. I have tried the following:
1/ In terminal I have opened python shell and written pip show mongoengine and it can detect the version and location which means that library is installed correctly.
2/ I have tried to run the code by removing the sudo required part then also code has executed.
Which strength the point that using sudo python3 pyfile_name.py is causing the problem.

QUESTION
I would like to develop web apps in Google colab. The only issue is that you need a browser connected to local host to view the web app, but Google colab doesn't have a browser inside the notebook.
But it seems that there are ways around this. For example run_with_ngrok is a library for running flaks apps in colab/jupyter notebooks
https://github.com/gstaff/flask-ngrok#inside-jupyter--colab-notebooks
When you use it, it gives a random address , "Running on http://.ngrok.io"
And somehow the webapp that's running on Google colab is running on that address.
This is a great solution for Flask apps, but I am looking to run webapps in general on Google Colab, not just Flask ones. Is there a general method for running webapps in colab/jupyter notebooks?
...ANSWER
Answered 2020-Jan-14 at 22:57Here is an example that illustrates starting a webserver and serving resources to a Colab output frame.
https://colab.research.google.com/notebooks/snippets/advanced_outputs.ipynb#scrollTo=R8ZvCXC5A0wT
Colab caches served outputs so that notebooks will render without reexecution. For live servers, users will need to reexecute the code to start the server. But, afterwards, Colab will proxy requests from the output frame that reference localhost to the Colab backend.

So I have been messing around with coding a BMI calculator from an online program, I want the final output of data to say something like: "Based on your height of 75" and weight of 200lbs your BMI is: "
I can't really figure out how to pull the data that I have already prompted the user to write back into my final sentence, I am not super experienced in coding and see this is something a lot of people start with. Any help is appreciated, I see a lot of flak for people asking these questions since it seems to be the first project in colleges.
...ANSWER
Answered 2020-Jan-22 at 01:23You are almost there, you need to concat your string (like you did for BMI value) with variables, you prompted previously:
