Frontera is a web crawling framework consisting of crawl frontier, and distribution/scaling primitives, allowing to build a large scale online web crawler. Frontera takes care of the logic and policies to follow during the crawl. It stores and prioritises links extracted by the crawler to decide which pages to visit next, and capable of doing it in distributed manner.

QUESTION
When I run the code below, I get this error:
...ANSWER
Answered 2021-Dec-29 at 21:12V_inicial[0],V_inicial[1],V_inicial[2],V_inicial[3] should be an array, I have never use that function but I have been looking to the docummentation that you can read here:
https://docs.scipy.org/doc/scipy/reference/generated/scipy.integrate.solve_ivp.html
The function identifies V_inicial[0] as the y0 param and V_inicial[1] as the method param and when you write method='RK45' you are defining another value to method param. Try to use an array, and tell me about :)).
