Hi all, I’ve run into loading images in the look up table demo. Here’s the code: Loading the data FILE\_NAME = ‘\Users\Desktop\AICSTest.tif’ reader = AICSImage(FILE\_NAME) IMG = reader.data.astype(np.float32) print(IMG.shape) File “”, line 1 FILE\_NAME = ‘\Users\Desktop\AICSTest.tif’ ^ SyntaxError: (unicode error) ‘unicodeescape’ codec can’t decode bytes in position 0-1: truncated \UXXXXXXXX escape I’ve also tried normalizing the string in a number of ways and I get a File Not Found error. Loading the data FILE\_NAME = r’\Users\Desktop\AICSTest.tif’ reader = AICSImage(FILE\_NAME) IMG = reader.data.astype(np.float32) ​ print(IMG.shape) * * * FileNotFoundError Traceback (most recent call last) in 1 FILE\_NAME = r’\Users\Desktop\AICSTest.tif’ ----\> 2 reader = AICSImage(FILE\_NAME) 3 IMG = reader.data.astype(np.float32) 4 5 print(IMG.shape) Any one have any thoughts on this? Thanks, Aidan ---

can you remind me if you are using windows? or Mac? ---

Windows! Sorry for not clarifying. Aidan ---

a couple of things to check: (1) make sure your file realy exists (2) your file path does not seem to be correct full path, should it be something like C://Users/… (3) you can also try a relative path, namely, copying your tiff file to the same directory as where you start your jupyter. then, use filename only to load the image ---

Hi Jianxu, Option number 3 worked! I’m not sure why loading from my desktop didn’t work as the file definitely exists but this works for me! Best, Aidan ---

In a normal string, try doubling the backslashes in your paths. For example, ’\Users\Desktop\AICSTest.tif’ becomes ‘\\Users\\Desktop\\AICSTest.tif’. Python interprets a single backslash as an “escape” character and is trying to interpret “\U” as a special thing. Your “r” string would have worked but I believe was missing the C: drive designator, as Jianxu mentioned. You should then be able to load files from your desktop. ---

Thanks all for the responses. I managed to upload an image by loading the file into the jupyter path. When I exported I used r’\C:\Users\elcid\DeskTop\test\_segmentation.tiff’ path which worked (a few other permutations did not). Best, Aidan
