Reading "a flat, binary array of 16-bit signed, little-endian (LSB) integers" from file in python

I’m trying to read a old file of snow data from here, but I’m having a ton of trouble just opening a single file and getting data out. In the user guide, it says "Each monthly binary data file with the file extension ".NSIDC8" contains a flat, binary array of 16-bit signed, little-endian (LSB) integers,… Read More Reading "a flat, binary array of 16-bit signed, little-endian (LSB) integers" from file in python

Saving Binary Data with javascript changes bytes

I have some binary data im trying to save to a file using javascript. The backend sending the data is written in python. Here is the backend code for sending the binary data using flasks send_file: def exportSavedata(characterId): character = Characters.query.filter_by(id=characterId, user_id=current_user.id).first() savedata = character.savedata exportFolder = os.path.join(os.path.dirname(os.path.abspath(__file__)), ‘exportSavedata’) if not os.path.isdir(exportFolder): os.mkdir(exportFolder) filename =… Read More Saving Binary Data with javascript changes bytes

Read binary file chunk by chunk in C

Im new to C, and used to python. But because of current situation in the world my primary computer was destroyed and all I left with is 12 years old laptop. Python would not work really good there. My goal is to create encryption algorithm. Currently its fairly simple, but I will upgrade it later… Read More Read binary file chunk by chunk in C

How to write multiple lists into a text file where each list is written into a new line?

I have two python lists: a_list = [1, 2, 3] b_list = [4, 5, 6] How can I do the following: create new text file —> convert lists to json string —> write lists into the file (each list should have its own line in the file) —> open the file —> read each line… Read More How to write multiple lists into a text file where each list is written into a new line?

Python Request send image

I have a fastapi app where one of my endpoints reads as: @app.post( "/testing", name="testing", tags=["pluggin"], ) def testing(images: List[bytes] = File(…)): #do whatever how can I send a request with an image so the endpoint will read it correctly? Right now I have: import requests f = io.BytesIO(file readed in binary) files = {‘file’:… Read More Python Request send image

mediation::mediate does not support more than two levels per model

When I fit a mediation model using mediation::mediate, like this: library(mediation) set.seed(30) df <- data.frame(x = runif(100), x2 = runif(100), y = runif(100), m = runif(100), p_id = sample(1:5, 100, replace = TRUE), item = sample(LETTERS, 100, replace = TRUE)) fit.totaleffect <- lmer(y ~ (1|item) + (1|p_id) + x + x2, data = df) fit.mediator… Read More mediation::mediate does not support more than two levels per model

Remove items from one list if they contain strings from another list

I’m looking for the most efficient way to remove items from one list if they contain strings from another list. For example: B list contains: TomWentFishing SueStayedHome JohnGoesToSchool JimPlaysTennis A list contains: GoesToSchool SueStayed C list should contain: TomWentFishing JimPlaysTennis I’ve used this code, but it takes up a lot of time as the lists… Read More Remove items from one list if they contain strings from another list

Can Some one explain why I get these output?

I am new to c. My Question. Why do some numbers end up negative when the value was positive? Why do some small numbers end up with a huge magnitude when typecast to unsigned? #include <stdio.h> #include <stdbool.h> #include <limits.h> void typecast(int a) { unsigned b = (unsigned) a; unsigned char c = (unsigned char)… Read More Can Some one explain why I get these output?

Serialising compressed data to JSON produces a larger outcome than uncompressed

I have some code which takes a string and if it is above a given threshold, it compresses it. The result is then serialised to JSON and converted into an Azure Service Bus Message object. The problem is that the compressed version is coming out at larger than it would have been had I left… Read More Serialising compressed data to JSON produces a larger outcome than uncompressed

How can I Get, Edit and Set Gradient Matrix in Training of Keras Model?

I am creating a sparse neural network as described in the image below. Keras only provides a dense layer and we can’t choose how many neurons we want to be connected to the previous layer. For implementing this using Keras, I am trying to implement the following approach: 1- Get the Gradient Matrix of each… Read More How can I Get, Edit and Set Gradient Matrix in Training of Keras Model?
