Question

我使用erlport在erlang和python之间传递数据，遵循以下示例： http://erlport.org/docs/python.html

我正在调用的python文件只包含以下行：

import pandas as pd

我收到错误：

** exception error: {python,'exceptions.AttributeError',
                            "'function' object has no attribute 'lower'",
                            [{<<"/anaconda/lib/python2.7/site-packages/pandas/core/format.py">>,
                              1701,<<"detect_console_encoding">>,
                              <<"if not encoding or 'ascii' in encoding.lower():  # try again for something bette"...>>},
                             {<<"/anaconda/lib/python2.7/site-packages/pandas/core/config_init.py">>,
                              234,<<"<module>">>,
                              <<"cf.register_option('encoding', detect_console_encoding(), pc_encoding_doc,">>},
                             {<<"/anaconda/lib/python2.7/site-packages/pandas/__init__.py">>,
                              25,<<"<module>">>,<<"import pandas.core.config_init">>},
                             {<<"/Documents/data-algorithms/Alg"...>>,
                              3,<<"<module>">>,<<"import pandas as pd">>},
                             {<<"/Documents/testki"...>>,
                              237,<<"_incoming_call">>,
                              <<"f = __import__(module, {}, {}, [objects[0]])">>},
                             {<<"/Documents/te"...>>,
                              245,<<"_call_with_error_handler">>,<<"function(*args)">>}]}
     in function  erlport:call/3 (src/erlport.erl, line 234)
     in call from algo_tester:start/0 (src/algo_tester.erl, line 27)

我可以通过在/anaconda/lib/python2.7/site-packages/pandas/core/config_init.py中注释掉以下两行来消除错误：

234        cf.register_option('encoding', detect_console_encoding(), pc_encoding_doc,
235                            validator=is_text)

但是打印不再有效。

有没有人遇到过这个？
