Question

在我输入的程序中：将matplotlib导入为pt，我收到以下错误：

  File "C:\Users\hh\Anaconda3\lib\site-packages\numpy\__config__.py", line 5
    blas_mkl_info={'libraries': ['mkl_core_dll', 'mkl_intel_lp64_dll', 'mkl_intel_thread_dll'], 'library_dirs': ['C:\Users\hh\Anaconda3\\Library\\lib'], 'include_dirs': ['C:\Users\hh\Anaconda3\\Library\\include'], 'define_macros': [('SCIPY_MKL_H', None), ('HAVE_CBLAS', None)]}
                                                                                                                ^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

为什么会发生这种情况以及我可以采取哪些措施来改变这种情况？

这是它所指的文件：

# This file is generated by C:\Minonda\conda-bld\numpy-1.11_1475607650950\work\numpy-1.11.2\setup.py
# It contains system_info results at the time of building this package.

你的路径字符串中缺少（几个）转义反斜杠：

'C:\Users\hh\Anaconda3\\Library\\lib'

这里python将尝试将\U解释为unicode转义序列的开头（参见例如https://docs.python.org/2/reference/lexical_analysis.html#string-literals）。

正如您在此字符串的部分内容中所做的那样，您应该将\替换为\\：

'C:\\Users\\hh\\Anaconda3\\Library\\lib'

或使用原始字符串：

r'C:\Users\hh\Anaconda3\Library\lib'

修改我现在才意识到，这是由numpy / anaconda创建的文件而不是你自己。所以这可能值得为他们买票...我猜...

导入包会导致Anaconda中的Unicode错误
