Ok, so I’m building a new PILImage class that supports RAW images, so it’s named RawpyImage (because unlike PIL, Rawpy does support RAW files).
Here I’m trying to load the data into the dataset.
x_tfms=[RawpyImage.create]
y_tfms=[my_get_y, RawpyImage.create]
tfms = [x_tfms,y_tfms]
items = get_image_files(path=path_short)
splits = RandomSplitter(seed=2022)(items)
dsets = Datasets(items=items, tfms=tfms, splits=splits)
Output:
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)

Here’s my RawpyImage:
def load_raw_image(fn):
fn=str(fn)
with rawpy.imread(fn) as RAWobj:
return RAWobj.postprocess().copy()
class RawpyImage(Image.Image, metaclass=BypassNewMeta): #, metaclass=BypassNewMeta
"This is to copy class PILBase+PILImage"
_bypass_type=Image.Image
_show_args = {'cmap':'viridis'}
_open_args = {'mode': 'RGB'}
@classmethod
##@staticmethod
def create(cls,fn)->None:
return cls(load_raw_image(fn))
...
Now I’m trying to understand why this error shows up:
TypeError: __init__() takes 1 positional argument but 2 were given
Please help me get over this syntax issue…
Thanks
