1、问题

在使用Python中pandas读取csv文件时,由于文件编码格式出现以下问题:

Traceback (most recent call last): File "pandas/_libs/parsers.pyx", line 1134, in pandas._libs.parsers.TextReader._convert_tokens File "pandas/_libs/parsers.pyx", line 1240, in pandas._libs.parsers.TextReader._convert_with_dtype File "pandas/_libs/parsers.pyx", line 1256, in pandas._libs.parsers.TextReader._string_convert File "pandas/_libs/parsers.pyx", line 1494, in pandas._libs.parsers._string_box_utf8UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa0 in position 19: invalid start byteDuring handling of the above exception, another exception occurred:Traceback (most recent call last): File "E:/PyCharm 2017.3.4/helpers/pydev/pydevd.py", line 1668, in <module>  main() File "E:/PyCharm 2017.3.4/helpers/pydev/pydevd.py", line 1662, in main  globals = debugger.run(setup['file'], None, None, is_module) File "E:/PyCharm 2017.3.4/helpers/pydev/pydevd.py", line 1072, in run  pydev_imports.execfile(file, globals, locals) # execute the script File "E:/PyCharm 2017.3.4/helpers/pydev/_pydev_imps/_pydev_execfile.py", line 18, in execfile  exec(compile(contents+"/n", file, 'exec'), glob, loc) File "F:/OneDrive - emails.bjut.edu.cn/Program/Python/DCAE/test.py", line 18, in <module>  load_phenotypes_ABIDE2_RfMRIMaps() File "F:/OneDrive - emails.bjut.edu.cn/Program/Python/DCAE/Data/load_data.py", line 109, in load_phenotypes_ABIDE2_RfMRIMaps  pheno = pd.read_csv(pheno_path) File "E:/Python/Python35/lib/site-packages/pandas/io/parsers.py", line 678, in parser_f  return _read(filepath_or_buffer, kwds) File "E:/Python/Python35/lib/site-packages/pandas/io/parsers.py", line 446, in _read  data = parser.read(nrows) File "E:/Python/Python35/lib/site-packages/pandas/io/parsers.py", line 1036, in read  ret = self._engine.read(nrows) File "E:/Python/Python35/lib/site-packages/pandas/io/parsers.py", line 1848, in read  data = self._reader.read(nrows) File "pandas/_libs/parsers.pyx", line 876, in pandas._libs.parsers.TextReader.read File "pandas/_libs/parsers.pyx", line 891, in pandas._libs.parsers.TextReader._read_low_memory File "pandas/_libs/parsers.pyx", line 968, in pandas._libs.parsers.TextReader._read_rows File "pandas/_libs/parsers.pyx", line 1094, in pandas._libs.parsers.TextReader._convert_column_data File "pandas/_libs/parsers.pyx", line 1141, in pandas._libs.parsers.TextReader._convert_tokens File "pandas/_libs/parsers.pyx", line 1240, in pandas._libs.parsers.TextReader._convert_with_dtype File "pandas/_libs/parsers.pyx", line 1256, in pandas._libs.parsers.TextReader._string_convert File "pandas/_libs/parsers.pyx", line 1494, in pandas._libs.parsers._string_box_utf8UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa0 in position 19: invalid start byte

我认为该问题是由于文件编码格式不是'utf-8'所导致的,因此,尝试将文件格式进行转换,转换方式如下:

首先使用txt文本打开文件,然后另存为,在右下角将编码改为‘UTF-8',点击保存即可
