I have a time series of very large matrices. I am trying to speed up the process and was wondering the most optimal way to do this. The two things that came to mind are to parallelize the process using numba or to apply a function to the matrices such as with np.apply_along_axis. Speed and memory complexity are very important.

5-digit-year in date export (52164-01-19 00:00:00+00)
I received a data export from an unspecified source system, which includes dates in the format of: 52164-01-19 00:00:00+00 52992-08-12 04:29:36+00 52838-10-19 04:08:32.999936+00 54022-03-12 17:20:36.999936+00 I was told that the error is caused by a faulty conversion of unix to datetime (seconds and milliseconds). We came up with a possible approach to refactor the date in python, by separating the
Python does something every 5 minutes
i need to check data on an API. The API is refreshed with new data every 5 minutes (10:00, 10:05, 10:10 etc…) I don’t want to use time.sleep(300) because i want my script to do something at 10:05:03, then 10:05:03 etc. and not 5 min avec the script started (maybe it started at 10h12 How can i build this? Thanks
In Discord.py, is it possible to wait for a variable to change from a different part of the code than the variable changes?
I tried using time.sleep(), but instead of waiting for the variable it paused the whole code, not allowing the variable to change. This is my code: I can’t figure out what to replace time.sleep(1.0) with. Answer You can use await asyncio.sleep(1) instead. Asyncio.sleep works like time.sleep, but it doesn’t block the entire code execution. It stops only one event. Meanwhile,
Setting Time with interval of 1 minute
I have a dataset which comprises of minutely data for 2 stocks over 3 months. I have to create date in the first column and time (with interval of 1 minute) in the next column for 3 months. I am attaching the snap of 1 such data set. Kindly help me to solve this problem. Data Format Answer -Create 3
how can I strip the 00:00:00 from a date in python
This might be a really simple question, but I’m using the code below to add 1 day to a date and then output the new date. I found this code online. this code works but the output its gives me looks like this but for the rest of my code to run properly I need to get rid of the
Optimizing python script to produce output faster (Variable Assignment)
I am using python for optimization purposes. I made a graph using Networkx library with 1100 nodes. The python script includes the following lines. In the next step, some random numbers are generated as follows: I compute the distance between nodes in the graph using the following function. Finally, I defined the variable “shipping_cost” as: Every line of the above
how do i get only the time in python without the date and year?
I need to get time in python and i am using time.ctime() and it returns this Thu Jul 8 15:37:26 2021 But i only need 15:37:26 and i cant figure out how to get only this and not the date and year. I already tried using datetime where i could not figure it out either so im trying with time
Python print the same timestamp the same anywhere
I’m given a timestamp in seconds, and I ‘inherited’ a function to print it in human-readable form, but the function is locale-specific; that is, it matters what time zone the host is configured for. I want to print that time as GMT no matter what time zone I’m in. For example, here’s the sequence on a computer in Mountain Time
How to optimize time while converting list to dataframe?(Part II)
I didn’t get any proper answers to my previous question: How to optimize time while converting list to dataframe? Let me explain the example more: Let’s consider the data frame more precisely as I want the output dataframe when converted to csv as The character PH,AG, AD,N should not be mapped. It can be any character. This works fine while
