Validation data set not loading properly

Part 1 (2019)
1

code:

np.random.seed(41)
data = ImageDataBunch.from_folder(path, train=“No_findings”, valid =“Covid-19”,
ds_tfms=get_transforms(), size=(256,256), bs=32, num_workers=4).normalize()

error:

ImageDataBunch;

Train: LabelList (500 items)
x: ImageList Image (3, 256, 256),Image (3, 256, 256),Image (3, 256, 256),Image (3, 256, 256),Image (3, 256, 256)
y: CategoryList No_findings,No_findings,No_findings,No_findings,No_findings
Path: C:\Kannadasan\Covid19\DarkCovidnet\COVID-19-master\X-Ray Image DataSet;

Valid: LabelList (125 items)
x: ImageList Image (3, 256, 256),Image (3, 256, 256),Image (3, 256, 256),Image (3, 256, 256),Image (3, 256, 256)
y: CategoryList 0,0,0,0,0
Path: C:\Kannadasan\Covid19\DarkCovidnet\COVID-19-master\X-Ray Image DataSet;

If you look at the y: CategoryList in Valid datset, it is showing as 0,0,0,0,0…

I think this is the error.

Please help to fix this error.

Thanks
