kandi X-RAY | intervaltree Summary
For a university project, I needed an Interval Tree data structure, and what’s out there was not satisfying, so I built my own. It supports insertion, deletion and queries, supports multiple entries per interval, is not static and not concurrency-safe. For a simple usage example, have a look at the de.tinloaf.intervaltree.test package. You can also have a look at the api documentation at [

QUESTION
I am trying to build an app from a python file (Mac OS) using the py2app extension. I have a folder with the python file and the "setup.py" file.
- I first tested the app by running
python setup.py py2app -A
in the terminal and the dist and build folder are successfully created and the app works when launched. - Now when I try to build it non-locally by running the command
python setup.py py2app
in the terminal, there are various "WARNING: ImportERROR" messages while building and finally aerror: [Errno 2] No such file or directory: '/opt/anaconda3/lib/python3.8/site-packages/rtree/lib'
error.
How can I fix this? I've tried to delete anaconda fully as I don't use it but it seems to still want to run through it. Additionally, I have tried to run the build command using a virtual environment but I end up having even more import errors.
*I Left out a lot of the "skipping" and "warning" lines using "..." for space
ANSWER
Answered 2022-Mar-13 at 16:13The error error: [Errno 2] No such file or directory: '/opt/anaconda3/lib/python3.8/site-packages/rtree/lib'
was caused by py2app trying to build the program bundle using a non-existent interpreter. This means that even if you try to uninstall a manager like Anaconda, it still has option logs somewhere on your mac.
The fix:
- Open the terminal and type the command
type -a python
.
- You will see similar lines

I am trying to deploy my first web app on Heroku however I am getting a PyObjc error while pushing the code. I am doing this on a Mac Machine. This predictive application is developed using Flask. I do not know why this error is occurring as I do not have the PyObjc in my requirements.txt

appears to be Apple-only:
Simple package for registering an app with apple Launch Services to handle UTI and URL. See Apple documentations for details.
I suspect you don't need that, either. Did you create your requirements.txt
from a pip freeze
? There's likely a bunch of stuff in there you don't need.
I suggest you review that file and remove anything you aren't directly depending on. pip
will find transitive dependencies (dependencies your dependencies depend on) and install them automatically.
Prune that file, commit, and redeploy.

I have a dataframe that contains columns of various item recommendations, and the elements are represented as a list (in reality all lists have 10 elements in them, but this is less important):

QUESTION
Say I want to store ordered values where the key values represent a lower bound. Like this example:
d = {1: "pear", 4: "banana", 7: "orange"}
I can access the first object by d[1]
. Say I want to store it so that I can access the first object "pear"
by calling for any value between [1,4)
. If I input any "keyvalue"
between [4,7)
I want "banana"
to be returned. Is there any type of data structure like that in python? I found intervalTrees
, but it looked a bit more advanced than what I was looking for. In intervalTrees
the intervals which are the keys, can be overlapping and I don't want that. Or maybe it is not a dictionary of any type I want since you can mix datatypes as keys in one dictionary. What do you think?
EDIT: From the tip I got, this would be a working code:
...ANSWER
Answered 2021-Oct-17 at 21:12The data structure you're looking for is a binary search tree (BST), and preferably a balanced BST. Your dictionary keys are the keys of the BST, and each node would just have an additional field to store the corresponding value. Then your lookup is just a lower-bound / bisect-left on the keys. Looking up Python implementations for Red-Black trees or AVL trees returns many possible packages.
There is no builtin library for always-sorted data. If you never need to add or delete keys, you can use bisect with (key, value) tuples in a sorted list.
For a pure Python implementation that allows modification, I would recommend checking out SortedDict from the SortedContainers library. It's built to be a drop-in replacement for BST's, is very usable and tested, and claims to outperform pointer-based BST's in memory and speed on reasonably sized datasets (but does not have the same asymptotic guarantees as a BST). You can also provide a custom key for comparing objects of different types.

QUESTION
Hi I'm building on an application that gets events from json file sample like this:
...ANSWER
Answered 2021-Sep-05 at 22:49It's because you are using Codable
, and it is trying to decode id
from the JSON. The id
isn't in your JSON, and I can see you want each new instance to create its own ID.
If you printed an error in a catch statement, by using do-try-catch
rather than try?
, you would have seen the following:
keyNotFound(CodingKeys(stringValue: "id", intValue: nil), Swift.DecodingError.Context(codingPath: [_JSONKey(stringValue: "Index 0", intValue: 0)], debugDescription: "No value associated with key CodingKeys(stringValue: "id", intValue: nil) ("id").", underlyingError: nil))
Basically, they is no value associated with the key id
, because the key is not in the JSON.
You need to create custom CodingKey
s to exclude id
from being encoded/decoded:

Install intervaltree
You can use intervaltree like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the intervaltree component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
