Can someone please help with this?

urls = search_images_ddg('grizzly bear', max_images=100)
len(urls),urls[0]s

Can you please prit what urlread returns?
print(urlread(url,data={‘q’:term})
Maybe it returned an error message (a string) that cannot be decoded?

urlread now returns urls decoded as str per default, you can remove the .decode() from the function and it works.

Removed the .decode() recommended by @BresNet, fixed the issue. :slight_smile:

seems that the search_images_ddg() in (even the latest) fastbook still has the “.decode” in it.

urls = search_images_ddg('grizzly bear', max_images=100)
len(ims)

urls = search_images_ddg('grizzly bear', max_images=100)
len(ims)
urls = search_images_ddg('grizzly bear', max_images=100)
len(ims)

How do you remove the .decode function, since it is in /usr/local/lib/python3.7/dist-packages/fastbook/__init__.py which in the library path?
is it okay to remove it from inbuilt files?

It is fixed in the book’s repo. I guess it hasn’t published to pypy yet.

You can copy the whole function from fastbook/utils.py at 8be580737ee0cc17746a5ed68283150d489b3dc4 · fastai/fastbook · GitHub, add a new cell in a notebook, and run it. It will override the installed package’s function.
