QUESTION
I'm new to rust.
I'm trying to follow the example for implementing the from_str trait here
https://doc.rust-lang.org/std/str/trait.FromStr.html
But I keep getting this error pointing at 'return Err(Self::Err)'
...ANSWER
Answered 2021-Jun-03 at 04:49The function will return it last statement. Remove the last semicolon, and you could also remove the internal return statement, the result of the match statement will be returned.
Is there a better way? It looks like you are parsing a string to a enum, the create enum-utils does that. Instead of implementing the parser with boilerplate code you just derive it.
QUESTION
I have 3 tables. First there is Posts tables which looks like this
id post_creator 1 Mark 2 John 3 David 4 Ellie 5 Thomas 6 ElliotThere are 2 types of post. image post and text post. I have 2 different tables for them. Here's how text_posts table look like:
post_id post_text 1 lorem ipsum 4 lorem ipsum 5 lorem ipsumagain there's an image_posts table both follows id from posts table
post_id post_text post_image 2 lorem ipsum image_url 3 lorem ipsum image_url 6 lorem ipsum image_urlNow I dont care about post_image urls, all I want is to get post_creator from Post table along with post whether its in text_post table or image_post table I want the texts. How can I do that?
...ANSWER
Answered 2021-Apr-26 at 08:17I assume that you are using a SQL Db.
In this case, Posts and post_text/image_posts are a NtoN relationship so you should normalize the relationship as 2 1toN. In this case it ends with 1 table Post, 2 Table: Post_text and Post_img and another table that maintains the "history" of post per each user. You should create another table named Creates(id, user_id, post_id).
Then you can join the 2 table and obtain the post_creator.

I've created a random database of 100 soccer players, with randomly generated names, positions, and ability (1-5). I want to append the list so that it reviews the ability of each player and assigns a value (20-100) based on their ability. 1 ability = 20 value. 2=40, 3=60, 4=80, and 5=100. In excel, for example, I would do a vlookup to the ability (1-5) and apply the value based upon the ability number. How would I go about doing this in a Python list? Thanks

For the most part, I'm almost done. I just need to add list elements in the unordered list that is commented (I'll share the code below). There is an array called resources, which holds five objects with the following properties – title, href, and innerHTML.

Is it possible to change the height of the individual option in Semantic UI React? or Is there any way to override the CSS class. I can apply inline style on the drop-down component
...ANSWER
Answered 2021-Feb-08 at 02:23There are two ways to change or overwrite semantic-ui styles in react, one is use the !important param in your css module or modify the react index.css with the semantic-ui class name.
In your case to achieve this, you need to use dropdown with and , for specifying the exact item to modify:

QUESTION
I have a problem about implementing recommendation system by using Euclidean Distance.
What I want to do is to list some close games with respect to search criteria by game title and genre.
Here is my project link : Link
After calling function, it throws an error shown below. How can I fix it?
Here is the error
...ANSWER
Answered 2021-Jan-03 at 16:00The issue is that you are using euclidean distance for comparing strings. Consider using Levenshtein distance, or something similar, which is designed for strings. NLTK has a function called edit distance that can do this or you can implement it on your own.

Elliot's entry point is the function run_experiment, which accepts a configuration file that drives the whole experiment. In the following, a sample configuration file is shown to demonstrate how a sample and explicit structure can generate a rigorous experiment. The following file is a simple configuration for an experimental setup. It contains all the instructions to get the MovieLens-1M catalog from a specific path and perform a train test split in a random sample way with a ratio of 20%. This experiment provides a hyperparameter optimization with a grid search strategy for an Item-KNN model. Indeed, it is seen that the possible values of neighbors are closed in squared brackets. It indicates that two different models equipped with two different neighbors' values will be trained and compared to select the best configuration. Moreover, this configuration obliges Elliot to save the recommendation lists with at most 10 items per user as suggest by top_k property. In this basic experiment, only a simple metric is considered in the final evaluation study. The candidate metric is nDCG for a cutoff equal to top_k, unless otherwise noted.
