OpenCV Haar Cascade Creation - opencv

Question

I want to try create my own .xml file for my graduation project with this reference.
But I have a problem which stage 6 doesn't work.It gives error such as:
Traceback (most recent call last):
File "./tools/mergevec.py", line 170, in <module>
merge_vec_files(vec_directory, output_filename)
File "./tools/mergevec.py", line 120, in merge_vec_files
val = struct.unpack('<iihh', content[:12])
TypeError: a bytes-like object is required, not 'str'
I have found a solution which says find 0 size vector files and delete them.
But, I don't know which vector files are 0 size and how I can detect them.
Can you help about this please?

Answer 1

I was able to solve my problem when i changed it:
for f in files:
with open(f, 'rb') as vecfile:
content = ''.join(str(line) for line in vecfile.readlines())
data = content[12:]
outputfile.write(data)
except Exception as e:
exception_response(e)
for it:
for f in files:
with open(f, 'rb') as vecfile:
content = b''.join((line) for line in vecfile.readlines())
outputfile.write(bytearray(content[12:]))
except Exception as e:
exception_response(e)
and like before i changed it:
content = ''.join(str(line) for line in vecfile.readlines())
for it:
content = b''.join((line) for line in vecfile.readlines())
because it was waiting for some str, and now it is able to receive the binary archives that we're in need.
