读取二进制inpu的UnicodeDecodeError

Question

我尝试将代码从Python2.7移植到3.4。低于2.7就可以了。 我将导入一个Picoscope二进制文件，并在python3.4（ubuntu）下得到以下错误：

in __import_CS
data_A = bin_file_A.read(64)
File "/usr/lib/python3.4/codecs.py", line 313, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf3 in position 1: invalid continuation byte

代码片段如下：

^{pr2}$

Answer 1

您需要以二进制模式读取文件：

bin_file_A = open(infile_A, "rb")
bin_file_B = open(infile_B, "rb")
