Running the Lesson 11 notebook 08_data_block.ipynb

Part 2 (2019)

@exynos7 discovered two corrections that are needed to make 08_data_block.ipynb execute without error.

Here are the steps involved

  1. Define the function cos_1cycle_anneal:

Copy the following lines of code :

@annealer
def cos_1cycle_anneal(start, high, end): return [sched_cos(start, high), sched_cos(high, end)]

and paste them into the 05_anneal.ipynb notebook under the other schedule functions.

Note: The copied code is from the file nb_05.py (in the /exp folder). Do not edit the nb_05.py file.

Then execute the last cell in the notebook 05_anneal.ipynb:

!python notebook2script.py 05_anneal.ipynb,

which will regenerate a corrected nb_05.py file

  1. Add an in_train property to the Runner class:

Copy the this line of code:

self.in_train = False

and paste it into the 05b_early_stopping.ipynb notebook as the first line in the __init__ method of the Runner class, just before the line

callbacks = listify(callbacks)

Note: The copied line of code is from the file nb_05b.py (in the /exp folder). Do not edit the nb_05b.py file.

Then execute the last cell in the 05b_early_stopping.ipynb notebook:

!python notebook2script.py05b_early_stopping.ipynb`.

This regenerates a corrected nb_05b.py file

After you have completed these two steps, the notebook 08_data_block.ipynb should run successfully.
