I tried ignoring nans and setting the color bar limits to above 1, but nothing works.As a special service 'Fossies' has tried to format the requested source page into HTML format using (guessed) Python source code syntax highlighting (style: standard) with prefixed line numbers.ДЄlternatively you can here view or download the uninterpreted source code file.ДЇor more information about '_minimize.py' see the Fossies 'Dox' file reference documentation and the last Fossies 'Diffs' side-by-side code changes report: 1.8.0rc1_vs_1.8.0rc2.ДЎ ''' 2 Unified interfaces to minimization algorithms.

But if the solution is different every time, perhaps this RubikвЂ™s cube environment requires some additional modifications so that the neural net can learn how to solve for any given front of cube (i.e. Traditional rubikвЂ™s cube reinforcement learning projects aim to solve the cube completely, and through the training process the neural net learns what a solved cube is and how to get to it. One theory is that the environment does not clearly indicate what the goal is or that the neural net during learning doesnвЂ™t have a clear sense of the goal during each iteration. I'm also looking into making the input shape a 6x3x3 array instead of a vector with a length of 54, but that's for another post. The problem is that the neural network during training does not exhibit convergence, so I am looking into several possible theories why this is happening. This environment is adapted from this 'gym-Rubiks-Cube' repository. The initial starting point is 3 random rotations away from the solution.

I am developing a gym environment so that a neural net solves for the front of a rubik's cube thatвЂ™s randomly shuffled.
