   Using Windows, if you installed it using source code, may be this is happening to you. I just faced it and resolved it using a quick (its nasty but works) fix.

   1. open lsd.py and put a print(temp) just when temp has been created, this gives the path where temp file is created
   2. A file would be created every time at this location, but the name is not as per expected, due to some reasons. (EXPECTED: randomno+ntl.txt, ACTUAL: C - in my case)
   3. just replace temp by this new path(location of file+C) at two places - a) where it is read again b) in remove
   4. Done, should work!

   @getsanjeev great work!
   Sorrowly, it does not work for Linux. Probably, you have any ideas for it too?

   Yep!Just Replace 15th line code temp = os.path.abspath(str(np.random.randint( 1, 1000000)) + 'ntl.txt').replace('\\', '/') in this file "pylsd/pylsd/lsd.py" to temp='a'.
   I just run this code on windows

   Just replace 15th line and 20th line in pylsd/pylsd/lsd.py as follows:
   # temp = os.path.abspath(str(np.random.randint(1, 1000000)) + 'ntl.txt').replace('\\', '/')
temp = os.path.abspath(str(np.random.randint(1, 1000000)) + 'ntl.txt').replace('\\', '/').encode('utf-8')
# lsdlib.lsdGet(src, ctypes.c_int(rows), ctypes.c_int(cols), temp)
lsdlib.lsdGet(src, ctypes.c_int(rows), ctypes.c_int(cols), ctypes.c_char_p(temp))

   I upgraded the lsd algorithm version from 1.5 to 1.6, and solved the FileNotFoundError. Now it works on python3.
   You can install it with pip install pylsd2
