celluloid | Actor-based concurrent object framework for Ruby | Application Framework library

I want the green rectangle to not disappear as it moves from one value to another in matrix b. For example, the rectangle is around 0.24671953. Then the rectangle stays on this value. Then another rectangle appears onto the next value which is 0.25959473. Then another rectangle appears on 0.41092171, with the previous two rectangles not disappearing.

I was trying the first simple animation from this page. I am clearly a beginner at making animations. I paste the code below.

I have implemented a simple randomized, population-based optimization method - Grey Wolf optimizer. I am having some trouble with properly capturing the Matplotlib plots at each iteration using the camera package.

I am running GWO for the objective function f(x,y) = x^2 + y^2. I can only see the candidate solutions converging to the minima, but the contour plot doesn't show up.

Do you have any suggestions, how can I display the contour plot in the background?

I am building a 'netflix' style app for practice. In it, I want the user to be able to find all movies of a certain genre by typing in the following url:

http://localhost:8080/movies/Adventure

But I seem to be going wrong somewhere, because the list returns null... here is my code:

I am trying to build an animated heatmap using celluloid. The x & y axis and color scale are the same but my code returns the weird output below.

My code uses seaborn, numpy, pandas, and celluloid and is simplified below:

I'm trying to revive an old Rails application I worked on several years ago. I'm using ruby 2.3.3 and rails 3.2.15 on the Heroku-16 stack with ClearDB for my MySQL database with the mysql2 adapter. When deploying to Heroku it succeeds on the deploy but crashes when it tries to start the app.

Full stack trace from the Heroku log (updated after fixing activerecord-import gem version per suggestion in first answer):

I made a plot of the projected world population that I've been struggling for days to animate. Here is the plot:

I picked up a 4 year old project written in Ruby 2.1.3 and Rails 4.1.8.

Very few of the gems were versioned but I've managed to get the project running locally by installing mysql2 0.3.20 as suggested in multiple other threads. Doing this required me to (on MacOS) downgrade openssl and mysql with brew install mysql@57 and brew install openssl@10.

I could then install mysql2 with by passing the correct libraries to it: gem install mysql2 -v 0.3.20 -- --with-mysql-config=/usr/local/opt/mysql@5.7/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl@1.0/lib --with-cppflags=-I/usr/local/opt/openssl@1.0/include

Everything works locally, all good.

I'm trying to deploy this project with Dokku on a Debian instance. Here's the readout from the push to dokku master including the error thrown when starting the Rails server:

I want to animate the process of finding the minimum point of a function by different gradient descent optimization methods. For this purpose, I am using matplotlib and celluloid packages. The problem is that it is not possible to fix the legend of the plot in animation and in each loop a new legend is added below the previous legend as you can see in the figure below. is there any way to fix the legend and avoid this problem?
