HOG | Histogram Of Oriented Gradients | Machine Learning library

not so long ago I started to practice with writing EOS smart contracts on my windows 10 computer. For this I needed to install among others, a Linux subsystem for Windows and Docker. In the last couple of days I noticed some pretty significant performance issues, when looking for the perpetrator in my task manager I came across Vmmem using up 1.8 GB of ram (which is quite a lot considering I have only 8GB on my laptop):

I Googled around some and figured out that this program handles virtual machines and such, and with that Docker. I don't have Docker Desktop or Ubuntu opened at the time of this screenshot, turned off the setting "Start Docker when you log in" and restarted my computer, but still this program is hogging up my RAM. As you may understand, it isn't worth it for me to keep this running in the background considering this EOS Development is a side-thing for me, hence I don't need to use Docker often. I would deem it a shame if I had to give up on this 'hobby' for performance issues so any help would be appreciated.

I tried to change a few lines from the original code however when I tried to run , I got error that say 'AttributeError: module 'PngImageFile' has no attribute 'shape'. However, I had no problem when running the original code. What should I do to remove this error in my modified code?

Here is the original code :

So I tried the methods that were mentioned in the previously asked similar question but none of them works for my python file. I have been on it for two days and can't seem to find a solution how to run this file from C# form on button click.

IronPython doesn't work because the python script has libraries that cannot be imported in Ironpython.

Running it from cmd doesn't work because cmd starts and then gets closed in a second.

Here's the code:

A bit of background:

I am an amateur programmer, having picked up Haskell a few months ago, on my spare time, after a period of Mathematica programmning (my first language). I am currently going through my second Haskell book, by Will Kurt, but I still have miles to go to call myself comfortable around Haskell code. Codeabbey has been my platform for experimentation and learning so far.

I have written a piece of code to generate permutations of a given number, that deals with possible duplicate numbers, so for 588 it will internally generate 588, 858 and 885.

However, because I want to scale to pretty big input numbers (think perhaps even a hundred digits long), I don't want to output the whole list and then perform calculations on it, instead every number that is generated is checked on the spot for a certain property and if it has it, well, we have a winner, the number is returned as output and there's no need to go through the rest of the humongous list. If sadly no desired number is found and we unsuccessfully go through all possible permutations, it outputs a "0".

I have also opted to make it a command line program to feed values to it via gnu parallel for faster work.

So here is the code

Someone asked me an interview question: write a function match(s, t) to decide if a string s is a generalized substring of another string t. More concretely, match should return True if and only if removing some characters in t can equalize it to s. For example, match("abc", "abbbc") is True, because we can remove the two extra bs in t.

Surely the interviewer is expecting some kind of recursive solution, but I'm feeling adventurous and wrote

I have the example plot shown below. How can I make the first and third x-axis tick horizontal and the second and fourth tick vertical?

I have a dataframe df that has a column containing text df['text'] (articles from a newspaper, in this case). How can I get a count of the rows in df['text'] that have a word count above some threshold of n words?

An example of df is shown below. Each article can contain an arbitrary number of words.

I have an express server in a node app. I need to be able to run this node app with the debugger. I also need to be able to stop and restart the server easily without binding up the port it runs on. I need to tap into the shutdown to do some cleanup, which I do like this:

I need to reduce the memory required by the KeDei TFT library used with the Osoyoo 3.5" TFT touch screen display shield for Arduino Uno and ATmega 2560. When I try writing a simple Arduino application that uses the TFT display with the KeDei library, most of the available memory on the Arduino is taken up by the library itself.

Unfortunately I have discovered that while an ATmega 2560 does have the necessary amount of memory, the KeDei TFT library does not provide correct touch coordinates when the TFT display is used with that device so the ATmega 2560 is not feasible unless Osoyoo customer support comes though with a solution.

Investigating the library source code, I found in the file KeDei_font.cpp a bitmap font table being used to generate the characters displayed. This bitmap font table is an array, unsigned char font16_B[96][16] and appears to be the main memory hog. This array contains bitmap fonts for the ASCII characters from the space character, 0x20, to the tilde character, 0x7e.

One thing that I have done is to reduce the number of characters by eliminating the lower case letters and transforming lower case letters to upper case. This results in a table const unsigned char font16_B[59][16] which is a bit more than half the size of the original table.

With this approach I also eliminate a few other punctuation type characters but as long as I'm displaying only alphanumeric characters and spaces, this will work.
