在上述站点上编译"process.py"时发生错误.
An error occurred when compiling "process.py" on the above site.
python tools/process.py --input_dir data -- operation resize --outp
ut_dir data2/resize
data/0.jpg -> data2/resize/0.png
回溯(最近通话最近一次):
Traceback (most recent call last):

(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte
错误原因是什么?Python的版本是3.5.2.
What is the cause of the error?Python's version is 3.5.2.
推荐答案
Python尝试将字节数组(假定为utf-8编码字符串的bytes)转换为Unicode字符串().当然，此过程是根据utf-8规则进行的解码.尝试此操作时，会遇到utf-8编码的字符串中不允许的字节序列(即位置0处的0xff).
Python tries to convert a byte-array (a bytes which it assumes to be a utf-8-encoded string) to a unicode string (str). This process of course is a decoding according to utf-8 rules. When it tries this, it encounters a byte sequence which is not allowed in utf-8-encoded strings (namely this 0xff at position 0).
由于您没有提供我们可以查看的任何代码，因此我们只能猜测其余的代码.
Since you did not provide any code we could look at, we only could guess on the rest.
从堆栈跟踪中，我们可以假定触发操作是从文件(contents = open(path).read())中读取.我建议以这种方式重新编码:
From the stack trace we can assume that the triggering action was the reading from a file (contents = open(path).read()). I propose to recode this in a fashion like this:
with open(path, 'rb') as f:
contents = f.read()
open()中的模式说明符中的b指出该文件应被视为二进制文件，因此contents将保留为bytes.这样不会发生解码尝试.
That b in the mode specifier in the open() states that the file shall be treated as binary, so contents will remain a bytes. No decoding attempt will happen this way.
