Question

无法导入sklearn。第一次导入sklearn时，显示以下内容：-

 Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/sklearn/__init__.py", line 134, in <module>
    from .base import clone
  File "/usr/local/lib/python2.7/dist-packages/sklearn/base.py", line 13, in <module>
    from .utils.fixes import signature
  File "/usr/local/lib/python2.7/dist-packages/sklearn/utils/__init__.py", line 10, in <module>
    from .validation import (as_float_array,
  File "/usr/local/lib/python2.7/dist-packages/sklearn/utils/validation.py", line 23, in <module>
    from ..externals.joblib import Memory
  File "/usr/local/lib/python2.7/dist-packages/sklearn/externals/joblib/__init__.py", line 127, in <module>
    from .parallel import Parallel
  File "/usr/local/lib/python2.7/dist-packages/sklearn/externals/joblib/parallel.py", line 27, in <module>
    from .format_stack import format_outer_frames
  File "/usr/local/lib/python2.7/dist-packages/sklearn/externals/joblib/format_stack.py", line 35, in <module>
    generate_tokens = tokenize.tokenize
AttributeError: 'module' object has no attribute 'tokenize'

然后，我重新导入它（在第一次尝试后立即），它向我显示了这个：-

    Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/sklearn/__init__.py", line 133, in <module>
    from . import __check_build
ImportError: cannot import name __check_build

我通过执行以下提到的步骤来重新安装sklearn，但问题仍然相同。

步骤：-

pip uninstall sklearn
pip uninstall scikit-learn
pip install sklearn

另一方面，我不知道它与该nltk库有什么关系，因为当我尝试import nltk时，它会产生相同的错误。 nltk导入时的错误如下所示。

    Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/nltk/__init__.py", line 128, in <module>
    from nltk.chunk import *
  File "/usr/lib/python2.7/dist-packages/nltk/chunk/__init__.py", line 157, in <module>
    from nltk.chunk.api import ChunkParserI
  File "/usr/lib/python2.7/dist-packages/nltk/chunk/api.py", line 13, in <module>
    from nltk.parse import ParserI
  File "/usr/lib/python2.7/dist-packages/nltk/parse/__init__.py", line 79, in <module>
    from nltk.parse.transitionparser import TransitionParser
  File "/usr/lib/python2.7/dist-packages/nltk/parse/transitionparser.py", line 21, in <module>
    from sklearn.datasets import load_svmlight_file
  File "/usr/local/lib/python2.7/dist-packages/sklearn/__init__.py", line 134, in <module>
    from .base import clone
  File "/usr/local/lib/python2.7/dist-packages/sklearn/base.py", line 13, in <module>
    from .utils.fixes import signature
  File "/usr/local/lib/python2.7/dist-packages/sklearn/utils/__init__.py", line 10, in <module>
    from .validation import (as_float_array,
  File "/usr/local/lib/python2.7/dist-packages/sklearn/utils/validation.py", line 23, in <module>
    from ..externals.joblib import Memory
  File "/usr/local/lib/python2.7/dist-packages/sklearn/externals/joblib/__init__.py", line 127, in <module>
    from .parallel import Parallel
  File "/usr/local/lib/python2.7/dist-packages/sklearn/externals/joblib/parallel.py", line 27, in <module>
    from .format_stack import format_outer_frames
  File "/usr/local/lib/python2.7/dist-packages/sklearn/externals/joblib/format_stack.py", line 35, in <module>
    generate_tokens = tokenize.tokenize
AttributeError: 'module' object has no attribute 'tokenize'

如果我在第一次导入后立即重新导入nltk，就像sklearn所做的那样，它将向我显示：-

    Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/nltk/__init__.py", line 128, in <module>
    from nltk.chunk import *
  File "/usr/lib/python2.7/dist-packages/nltk/chunk/__init__.py", line 157, in <module>
    from nltk.chunk.api import ChunkParserI
  File "/usr/lib/python2.7/dist-packages/nltk/chunk/api.py", line 15, in <module>
    from nltk.chunk.util import ChunkScore
  File "/usr/lib/python2.7/dist-packages/nltk/chunk/util.py", line 13, in <module>
    from nltk.tag.mapping import map_tag
  File "/usr/lib/python2.7/dist-packages/nltk/tag/__init__.py", line 63, in <module>
    from nltk.tag.sequential    import (SequentialBackoffTagger, ContextTagger,
  File "/usr/lib/python2.7/dist-packages/nltk/tag/sequential.py", line 25, in <module>
    from nltk.classify import NaiveBayesClassifier
  File "/usr/lib/python2.7/dist-packages/nltk/classify/__init__.py", line 86, in <module>
    from nltk.classify.megam import config_megam, call_megam
  File "/usr/lib/python2.7/dist-packages/nltk/classify/megam.py", line 29, in <module>
    from nltk import compat
ImportError: cannot import name compat
