02_production: show_batch() doesn't show any image

[rage2050a]

Hello,
I’m reading the fastbook on my Ubuntu 18.04 laptop which is installed conda, Jupyter Notebook, CUDA, ipywidget, etc.

I’ve successfully executed the code cells in the chapter 02_production, starting from
#hide
# !pip install -Uqq fastbook
import fastbook
fastbook.setup_book()
to
dls = bears.dataloaders(path)

(I think it should be noted that the code cell
im = Image.open(dest)
im.to_thumb(128,128)
showed an image of a bear.)

However,
dls.valid.show_batch(max_n=4, nrows=1)
showed no image, though it has executed something without error.

Same for the next four code cells that shows ResizeMethod.Squish, ResizeMethod.Pad, RandomResizedCrop, and aug_transforms.

I anyway executed until the cell
learn = cnn_learner(dls, resnet18, metrics=error_rate)
learn.fine_tune(4)
and after a while of running, the cell printed the table of epoch, train_loss, valid_loss, error_rate and time.

The next code cell,
interp = ClassificationInterpretation.from_learner(learn)
interp.plot_confusion_matrix()
this doesn’t output anything. (Expected an image of confusion matrix)

Has anyone got into similar problem?
How did you fix it?

Thank you.

I thought I should update a couple of packages for example IPython, however, my conda starts to stall with the message “failed with initial solve. Retrying with flexible solve.” for more than 24 hours.

I’ve uninstalled conda, re-installed conda and tons of packages (not only via conda but also some packaged forced me to use pip). After two weeks of struggle, it seems to be fixed finally.

The final error I saw was “UserWarning: image file could not be identified because WEBP support not installed”. It is fixed by removing pillow from conda and installing it via pip.

Here is the output from “conda list” in my fastbook environment.
