cannot identify image file <_io.BytesIO object at 0x7f2d80b2e770>

Thanks for your contribution!
But when I run the code, an error occurs:

Traceback (most recent call last):
File "runtime.py", line 42, in

IOError: cannot identify image file <_io.BytesIO object at 0x7f1be1801770>

My Pillow version is 5.1.0, and it seems like something related to the version.
Could anyone help me out?

Were you able to fix this? I'm facing the same issue.

I modified 'data=np.void(img)' in convert_cub_to_hd5_script.py(line 63) to 'data=np.array(img)', and reinstall the pil, then it works. I think the problem is related to the content of 'right_image' in hdf5 file. You can run a simple test on your hdf5 file:

dataset = h5py.File(PATH_TO_HDF5FILE, 'r') # PATH_TO_HDF5FILE is the path of birds.hdf5
dataset_keys = [str(k) for k in dataset['train'].keys()]
example_name = self.dataset_keys[0]
example = self.dataset['train'][example_name]
byte_image = bytes(np.array(example['img']))
image = Image.open(io.BytesIO(byte_image))
image.show()

Hope it can help

I had the same question. But bug disappears when I use python3.5.

Run the code in python3.
