AttributeError: 'FileDataset' object has no attribute 'PixelRepresentation'

Question

import pydicom
filename = r"E:\Codes\Python\tt.dcm";
ds = pydicom.read_file(filename,force=True)
ds.pixel_array

then, this error occurs : AttributeError: 'FileDataset' object has no attribute 'PixelRepresentation' the error information : wrong reasons image

Please put the entire error message. Might be related to a bug. Thanks. — jose_bacoy, Mar 14 '18 at 13:23
Can you edit the file and set the value to 1 using a DICOM Editor then try again? will work on this later once I log into my personal laptop. Thanks. — jose_bacoy, Mar 14 '18 at 14:20
yes. It seems that it is expecting a value and python found no value. Thus the error. — jose_bacoy, Mar 14 '18 at 14:30
I add this code “ds.dir()”, then it print this dcm file 's attributes,however,these attributes don't contain 'PixelRepresentation',so I wonder whether this image's information is not complete，however i can show it on matlab ,so I am confused — zhangyaoyao, Mar 14 '18 at 14:38

I add this code:

ds.PixelRepresentation = 0

so My code is:

filename = r"E:\Codes\Python\tt.dcm";
ds = pydicom.dcmread(filename)
ds.PixelRepresentation = 0
print ds.dir()
plt.imshow(ds.pixel_array, cmap=plt.cm.bone)
plt.show()

then show this Image successfully. this code:

ds.PixelRepresentation = 1

It is also correct
