Applying io.imread to Dataframe Column
I have a dataframe df with a column 'Poster' full of links to jpeg images. If I apply
img_data = io.imread(url)
theres is no problem because I'm using an specific url.
I want to make something like this:
x = np.asarray(io.imread(df['Poster']).tolist())
and get a numpy array of 4 dimensions (number of images, h, w, channels)
python pandas numpy

Try this:
posters =
for poster in df['Poster']:
posters.append(np.asarray(io.imread(poster).tolist()))
A fancier way:
posters = [np.asarray(io.imread(poster).tolist()) for poster in df['Poster']]
