Python sees the file name but gives "[Errno 2] No such file or directory"

I am trying to get a bunch of images from a directory and python gives me this error: FileNotFoundError: [Errno 2] No such file or directory: 'File1.jpg'

But 'File1.jpg' is the first file in the directory. Here is the code including the error:

filenames = [os.path.join(dirname, fname) for fname in os.listdir(dirname)]

filenames = filenames[:100]
assert(len(filenames) == 100)

filenames = [fname_i for fname_i in os.listdir(dirname)
                if fname_i.endswith('.jpg')]

imgs = [plt.imread(fname)[..., :3] for fname in filenames]

fails with FileNotFoundError and the following traceback:

---------------------------------------------------------------------------

the first time, you're doing it right, adding directory name:

In [5]: filenames = [os.path.join(dirname, fname)
   ...:    ...:               for fname in os.listdir(dirname)]

but in your filter you're omitting to add directory name again.

That would be only repeats of Moinuddin's comment if it wasn't for a better solution: simply use glob to filter AND get absolute path:

import glob
filenames = glob.glob(os.path.join(dirname,'*.jpg'))
