Tutor for coding CNN

The project: I need a tutor to teach me how to code CNN in colab. My level: I have very good background on CNN and coding in general but I have never build my own CNN code. I sstarted to write the code in colab but I have some problems such as I don't know how I define the input size. The code I want to build: The beam response, duo a dynamic load, is depending on the strength of the beam. I want to use 2D CNN to predict the beam strength by feeding the algorithm with beam response. I have several cases of beam with different strength values. Also, I have the beam response of these cases at five points in each case. So, the input of CNN will be a matrix of five columns as you can see the the attached figure. in this way, we can treat the matrix as an image and train the CNN to predict the strength value. In this code, I will predict one value. I want to be able to change this in the future to predict 4 paramters for another expermint. Notes: you can teach me in diffrent way. For example, I can share with you my current incompleted code and you show me where are my mistakes. Or we can have vedio call. Or I send you qustions about my struggles and you tell me how to resolve it Important note: The aim of this project giving me the ability to of building a code by my own.
