Lesson 1 - code questions

colawhite · April 6, 2019, 5:42pm

Hi there,

I have played around with Lesson 1 notebook and the code is here:

colawhite/fastai-v3/blob/master/lesson1-pets-Copy2.ipynb

{
 "cells": [
  {
   "cell_type": "markdown",
   "metadata": {},
   "source": [
    "# Lesson 1 - What's your pet"
   ]
  },
  {
   "cell_type": "markdown",
   "metadata": {},
   "source": [
    "Welcome to lesson 1! For those of you who are using a Jupyter Notebook for the first time, you can learn about this useful tool in a tutorial we prepared specially for you; click `File`->`Open` now and click `00_notebook_tutorial.ipynb`. \n",
    "\n",
    "In this lesson we will build our first image classifier from scratch, and see if we can achieve world-class results. Let's dive in!\n",
    "\n",
    "Every notebook starts with the following three lines; they ensure that any edits to libraries you make are reloaded here automatically, and also that any charts or images displayed are shown in this notebook."
   ]
  },

So far I have two questions:

The show_batch function takes a long time to run and does not show the same images as shown in the example notebook. Since we have set up the random seed, I expect to see the same images. Does anyone what is causing the difference?

When I used ClassificationInterpretation to plot_top_losses, the image is not shown correctly. Does anyone have the same issue?
