Bossman told me to give my project more hierarchy and to add all those weird __init__.py files.
I don,t quite like all those boring empty files, so anyone got some bri'ish language "innit?" jokes or other awful puns to add as comments?8 -
python machine learning tutorials:
- import preprocessed dataset in perfect format specially crafted to match the model instead of reading from file like an actual real life would work
- use images data for recurrent neural network and see no problem
- use Conv1D for 2d input data like images
- use two letter variable names that only tutorial creator knows what they mean.
- do 10 data transformation in 1 line with no explanation of what is going on
- just enter these magic words
- okey guys thanks for watching make sure to hit that subscribe button
ehh, the machine learning ecosystem is burning pile of shit let me give you some examples:
- thanks to years of object oriented programming research and most wonderful abstractions we have "loss.backward()" which have no apparent connection to model but it affects the model, good to know
- cannot install the python packages because python must be >= 3.9 and at the same time < 3.9
- runtime error with bullshit cryptic message
- python having no data types but pytorch forces you to specify float32
- lets throw away the module name of a function with these simple tricks:
"import torch.nn.functional as F"
"import torch_geometric.transforms as T"
- tensor.detach().cpu().numpy() ???
- class NeuralNetwork(torch.nn.Module):
def __init__(self):
super(NeuralNetwork, self).__init__() ????
- lets call a function that switches on the tracking of math operations on tensors "model.train()" instead of something more indicative of the function actual effect like "model.set_mode_to_train()"
- what the fuck is ".iloc" ?
- solving environment -/- brings back memories when you could make a breakfast while the computer was turning on
- hey lets choose the slowest, most sloppy and inconsistent language ever created for high performance computing task called "data sCieNcE". but.. but. you can use numpy! I DONT GIVE A SHIT about numpy why don't you motherfuckers create a language that is inherently performant instead of calling some convoluted c++ library that requires 10s of dependencies? Why don't you create a package management system that works without me having to try random bullshit for 3 hours???
- lets set as industry standard a jupyter notebook which is not git compatible and have either 2 second latency of tab completion, no tab completion, no documentation on hover or useless documentation on hover, no way to easily redo the changes, no autosave, no error highlighting and possibility to use variable defined in a cell below in the cell above it
- lets use inconsistent variable names like "read_csv" and "isfile"
- lets pass a boolean variable as a string "true"
- lets contribute to tech enabled authoritarianism and create a face recognition and object detection models that china uses to destroy uyghur minority
- lets create a license plate computer vision system that will help government surveillance everyone, guys what a great idea
I don't want to deal with this bullshit language, bullshit ecosystem and bullshit unethical tech anymore.11 -
everything was going great, I was loving it,
then self happens
why should one pass self (current object refrance) to the constructor in python , why doesn't this keyword exist in python.
coming from java I always forget to add it.
just WHY?????9 -

Hi people first as you know my English is not very poor im sorry for that.
I try to make an automat a sprinkle water and a auto light on a interior garden in aquarium.
For that in python i use main thread, a class Water.py extends Threading and Light.py extends Threading
In the __init__.py file i put my main function that get argv for execution. One of my arguments is -v (--verbose)
I want to pass that args to my class instances.
-I don't want to make one parameter in my constructors because I think we don't passe verbose mode in parameter of constructor.
-I use global not working through de import.
Do you have some magic for me :/ ?6 -

Can someone explain the reasoning for why we can't use init instead __init__? I'm learning and this is breaking my brain.6

Okay so theres something stopping me from understanding how Object Oriented Programming works. im sorry ahead of time this will get messy..
SO in this case we will use python. well what if the object has more than two functions? like the __init__, func1, then func2 and func2 does something else but doesn't get called or would you have to call of of them like class.func1(), class.func2().
I just don't understand when it comes to how the functions interact or effect each other. and how they would work when you dont call that specific function. I see the use of oop i just cant wrap my head around certain things..15 -
If anyone has a moment.
curious if i'm fucking something up.

Informal python poll:
Do you put your __init__ functions at the top or bottom of your classes?
AKA:

def __init__(self):

or...

Scenario: Enabling yet another python test suite on vscode. No big deal.
I start the test init and discovery. Says it cant find the test files. Okay; usually the issue is there's no __init__.py in the test directory. It's okay we can fix that.
Oh wait it's still not working. Okay well this isnt good... After about an hour of searching, i finally find out that the file that vscode is discovering tests with doesnt exist... In fact the whole testing directory doesnt exist!
Okay so now what do i do... Reinstall? Doesnt work. Reinstall and delete the extension directory? Yes! Victory!
Dont know how i got a half-baked extension download but hey... Could've beem worse. -

Working on a portfolio project - I ran some tests, everything is all good - 100% passing. Computer freezes - pop_os has been giving me shit lately, so I have to restart. Fine.
I get back into code, i re-run pytest - nothing works. Python apparently can't find my modules anymore. I try a few things, nothing. Why? Who the fuck knows - "oh you need this conftest file", "oh you need to remove __init__ from this directory or that one", "oh it's a pytest version iss---" no, no, no - listen here you little shit, it was working two seconds ago. Tell me why and how software I wrote with the most basic ass package structure - literally TWO directories suddenly has no fucking clue how to import the modules. hmm? Even from within the app directory, app.server now no longer recognizes imports from app.main or app.database.
ALL of this worked. It works in new directories without dedicated venvs - it works in new directories with my global python install - it works with any one of my conda envs - it works on other computers - WHY doesn't it work in THIS directory all of a sudden?? Ugh.
What's terrible is that relative imports will probably solve it within the app dir, but the tests dir won't accept them. Moreover, vs code autocompletion can find all the modules, but python itself cannot. Fucking infuriating shit like this is.1 -
Hey everyone! I need your help!
So I am working on a game engine thingy called Polita. Now I want to import Polita's core module (`polita/polita.py`) into the `test/simple.py`, which contains a simple test (See the image). But when I tried to run `test/simple.py`, it saids `No module called 'polita'` (See the image) although I have added `__init__.py` to indicate that `polita` is a module.
Any ideas?6 -
