cereal | A C++11 library for serialization | Serialization library

The C++ serialization library cereal uses the acronym NVP several times in its documentation without mentioning what it means.

A quick web search brings up further hits related to boost serialization, and on first glance I couldn't spot a full spelling of the acronym either. It seems to be some kind of C++ serialization related slang.

What does it stand for?

Using python.

Trying to make a recipe program that tells me what meals(key) I can make based off of the current ingredients(list) that I have.

Here is my meal dictionary, the key is the meal and the value is the required ingredients:

Whenever I use Map.Entry::getKey in my streams for my public methods, I get an issue around my method not being static. I even tried making my method static, and it didn't work.

Below is the compile error I am getting from using Map.Entry()::getKey() :

I'd like to update values in a column ['D'] of my data frame based on the substrings contained in column ['A']

I have dataframe df, where column D is an exact copy of column A. Column A has list of different cereal names. But I want to check if A contains a certain word and if so, then column D updates to show that word.

For example, If A contains the word Bran then D should update to show Bran. And if column A contains none of the criteria we are looking for then it should return Other.

So far I have tried this, but I am not able to change the rest of the columns without any criteria words to 'Other'

I have a dataframe that looks something like this:

I want to replace the descriptions of the items with the most frequent description based on the group # or the first instance if there is a tie.

So in the example above: Chips Ketchup (1 instance) is replaced with Chips BBQ (2 instances) And Cereal Chocolate is replaced with Cereal Honey (First Instance).

Desired output would be:

If this is too complicated I can settle for replacing with simply the first instance without taking frequency into consideration at all.

Thanks in advance

I have a list of lists containing prices of items, the order in which these elements are in, also matter. I also have a dataframe with the items in these lists and their correlating prices. I'm trying to iterate through each list and basically replace the price element in the list of lists with the corresponding item. The problem I have is that there are two items with the same price. Currently my code is just adding both of these duplicate priced items to the list but I want it to create a separate list for both items.

Current code:

I'm trying to follow along here to use a speech recognition model. The model is in C++, and almost all of my experience is in Python.

I installed a virtual machine running Ubuntu, and still the installation procedure was failing for me. I decided to simply try to compile the model so that I could call it in a Python script, as seen at the bottom of the linked page.

I'm trying to use g++ to compile the .cpp model, but I keep getting an error saying that a library that I have installed is not found:

I have a file where I'm trying to read each line into a struct in C to further work with it.

The file looks like this:

I've tried to separate my server socket in a singleton. Here's the code:
