QUESTION
I want to compile my DQN Agent but I get error:
AttributeError: 'Adam' object has no attribute '_name',
ANSWER
Answered 2022-Apr-16 at 15:05Your error came from importing Adam with from keras.optimizer_v1 import Adam, You can solve your problem with tf.keras.optimizers.Adam from TensorFlow >= v2 like below:
(The lr argument is deprecated, it's better to use learning_rate instead.)
QUESTION
We have a site that has been working pretty well for the past 2 years. But we are actually seeing random peaks in the database load that make the site very slow for a few seconds.
These peaks only appear from a certain load on the server and are impossible to predict. More users = more peaks. Everything run very smoothly outside of those peaks (page load is < 300ms). CPU and RAM are not impacted by those peaks.
Spikes are especially visible in db connections were it can go from 100 connections to 1000 connections for 2 or 3 seconds. Then back to normal.
We have nothing in the PHP log, nothing in the slow query log (long_query_time = 0.1).
Server : Debian / MariaDB 10.3.31, Apache 2.4.38, PHP 7.3.31 All tables are InnoDB with primary keys. Connection by socket. Codeigniter 4.1.7. Redis cache.
What we already try :
Reboot the server / Restart Mysql
Slow query log with long_query_time = 0 for 24h then pt-query-digest on the result. Everything is ok.
General log for 3h when heavy traffic then pt-query-digest on the result. Everything is ok.
Explain on each request of the logs. Everything looks fine.
We no longer know where to look to find the source of the problem.

QUESTION
We want to send tutors an email with student info every time they fill out a form. When a tutor fills out the form for a student, the tutors email populates in column E for that student. Then, column F is changed to "No." We want to send emails only to tutors who have "No" in column F.
Currently, our function serves this purpose. However, we also want that after an email is sent, it changes the "No" in colF to "Yes" to prevent future emails. We tried to use a forloop but we aren't too savvy with coding, and it does not change "No" to "Yes" at all. Thanks in advance for any help!

Modified script:QUESTION
Our "Current Tutors" sheet has a list of tutor names in column N (shown as row [13] in the code). Column A is the # of students they have (row [0]) in the code.
Basically, we want to filter our Google Form choices so that only tutors with values of 0 or 1 in column A appear. Unfortunately, it looks like the "|" does not do the logical operation of 0 OR 1. It just returns tutor names who have 0 students.
We are not savvy with coding, so any down-to-earth explanation is appreciated!

QUESTION
I am going through a flutter course on Udemy: Complete Flutter App Development Bootcamp with Dart I am in the provider package chapter. as an intro to state management, we have the following example code to illustrate how effort consuming it is to pass state in between classes and widgets without the use of a state management tool. the code is as follows:
...ANSWER
Answered 2022-Mar-09 at 07:38Well that's a bad way of teaching state management in Flutter!
Flutter's built-in state management is great already. What you need is to look at the InheritedModel that allows you to inherit state all the way down the widget chain and to even pick an aspect of the state that you want to inherit.
Here is a video that explains how you can use InheritedModel in Flutter: https://www.youtube.com/watch?v=0vl35jtpsfs&list=PL6yRaaP0WPkUf-ff1OX99DVSL1cynLHxO&index=4&ab_channel=VandadNahavandipoor
QUESTION
Well, probably so dumb question but I am not sure even how to search for it, I am pretty new to github. What I do is just watching some tutorials and I want to download the code from the link shared with the tutorials which is to this repo. I want to clone only this directory but there is no "git clone" option for that project. It is only possible for me to clone whole project which has many unrelated code. Do I have to clone whole project(maybe the tutor want me to clone them all) or is there a way to or download only that part ?
...ANSWER
Answered 2022-Mar-06 at 21:37You can't clone a single directory. You need to clone the entire project.
QUESTION
I‘m trying to wrap my head around the meaning of the Landau-Notation in the context of analysing an algorithm‘s complexity.
What exactly does the O formally mean in Big-O-Notation?
So the way I understand it is that O(g(x)) gives a set of functions which grow as rapidly or slower as g(x), meaning, for example in the case of O(n^2):
where t(x) could be, for instance, x + 3 or x^2 + 5. Is my understanding correct?
Furthermore, are the following notations correct?
I saw the following written down by a tutor. What does this mean? How can you use less or equal, if the O-Notation returns a set?
Could I also write something like this?
...ANSWER
Answered 2022-Feb-26 at 15:06So the way I understand it is that O(g(x)) gives a set of functions which grow as rapidly or slower as g(x).
This explanation of Big-Oh notation is correct.
f(n) = n^2 + 5n - 2, f(n) is an element of O(n^2)
Yes, we can say that. O(n^2) in plain English, represents "set of all functions that grow as rapidly as or slower than n^2". So, f(n) satisfies that requirement.
O(n) is a subset of O(n^2), O(n^2) is a subset of O(2^n)
This notation is correct and it comes from the definition. Any function that is in O(n), is also in O(n^2) since growth rate of it is slower than n^2. 2^n is an exponential time complexity, whereas n^2 is polynomial. You can take limit of n^2 / 2^n as n goes to infinity and prove that O(n^2) is a subset of O(2^n) since 2^n grows bigger.
O(n) <= O(n^2) <= O(2^n)
This notation is tricky. As explained here, we don't have "less than or equal to" for sets. I think tutor meant that time complexity for the functions belonging to the set O(n) is less than (or equal to) the time complexity for the functions belonging to the set O(n^2). Anyways, this notation doesn't really seem familiar, and it's best to avoid such ambiguities in textbooks.
QUESTION
I'm trying to piece together the logic in this example. This is the normal code. FYI, I had a university tutor help me with this example but he's still trying to figure out how to explain it to me. The code is also done, this is just for my own knowledge of recursion.

printTriangle(5) calls printTriangle(4)
printTriangle(4) calls printTriangle(3)
printTriangle(3) calls printTriangle(2)
printTriangle(2) calls printTriangle(1)
printTriangle(1) calls printTriangle(0)
printTriangle(0) does nothing, but returns to printTriangle(1)
printTriangle(1) procedes with calling printStars(1)
printStars(1) prints a star and calls printStars(0)
printStars(0) does nothing and returns to printStars(1)
printStars(1) has nothing more to do and returns to printTriangle(1)
printTriangle(1) prints a linebreak and returns to printTriangle(2)
printTriangle(2) procedes with calling printStars(2)
printStars(2) prints a star and calls printStars(1)
printStars(1) prints a star and calls printStars(0)
printStars(0) does nothing and returns to printStars(1)

I notice if I want for the element to be find with the e.currentTarget.children when clicked it most be immediate after the class clicked and I am having a hard time doing in it.
Any help is more than welcome!

Answered 2022-Feb-25 at 00:52Not sure what $(e.currentTarget).(e.currentTarget)('.arrow') was meant to be, but one way to target the relative arrow is $(this).find('.titulo-arrow .arrow'). Also, to figure out if we're opening or closing I use a className and just test for it
QUESTION
The background doesn't fill the entire screen in landscape. How can I make it stretch all the way?
Here's my code:
...ANSWER
Answered 2022-Jan-22 at 01:33The problem seems to be because of scaledToFit, which tries to preserve the image's aspect ratio and so doesn't make the background extend all the way.
To fix, just make the background stretch as much as it can with .frame(maxWidth: .infinity). Make sure to put this modifier before background so that the color respects the new layout.
