ImportError: No module named 'pandas.indexes'
ImportError: No module named 'pandas.indexes'
导入 pandas 没有抛出错误，而是试图读取一个选择的 pandas 数据帧：
import numpy as np
import pandas as pd
import matplotlib
import seaborn as sns
sns.set(style="white")
control_data = pd.read_pickle('null_report.pickle')
test_data = pd.read_pickle('test_report.pickle')
回溯是 165 行，包含三个并发异常（不管是什么意思）。 read_pickle 与 pandas 版本 17.1 不兼容吗？我是 运行？如何解开我的数据框以供使用？

我在尝试使用 pandas 0.17.1 打开由 pandas 0.18.1 制作的腌制数据框时遇到了这个问题。
如果您使用的是 pip，请将 pandas 升级为：
pip install --upgrade pandas
如果您使用的是像 anaconda 这样的库，请使用：
conda upgrade pandas
如果您需要在您的计算机上安装两个版本的 pandas，请考虑使用 virtualenv
这是无需更新 pandas 或您使用的任何内容的解决方案。
如果您正在使用 python2
import cPickle
with open('filename.pkl', 'rb') as fo:
dict = cPickle.load(fo, encoding='latin1’)
如果您正在使用 python3
import pickle
with open('filename.pkl', 'rb') as fo:
dict = pickle.load(fo, encoding='latin1’)
使用 pickle 在不同版本的 pandas 中保存和加载通常不起作用。相反，使用 pandas.HDFStore。
当我需要更新 pandas 但还需要在以前的版本中使用 pickle 保存一些数据时，我返回并以 HDF 格式重新保存该数据，当时其他方法都不起作用。没问题了。
似乎适用于任何类型的 pandas 数据结构，甚至是多索引数据帧！简而言之，如果版本升级后 pickling 失败，请尝试 HDFStore；它更可靠（也更高效！）。
我在使用 python 2.7 创建 pkl 文件并尝试使用 python 3.6 读取它时出现此错误
我做了：
pd.read_pickle('foo.pkl')
成功了
在 pandas 0.23.4 中，有更好的方法来解决这个问题。使用 pandas.read_pickle 读取文件对象，如：
pd.read_pickle(open('test_report.pickle', 'rb'))
如果您想阅读腌制文本而不是文件，请执行
import io
pd.read_pickle(io.BytesIO(pickled_text))
如果您遇到错误 - ValueError: Unrecognized compression type: infer,
明确提及压缩类型。它可以是 None（无压缩）、gzip、bz2、xz 或 zip（取决于文件扩展名）之一。
pd.read_pickle(io.BytesIO(pickled_text), compression=None)
处理破坏 unpickling 的内部 API 更改的一种灵活方法是实现自定义 Unpickler 实例。
例如，pandas.indexes 模块已移至 pandas.core.indexes。我们可以编写一个 Unpickler，它相应地调整模块路径。为此，我们可以覆盖方法 find_class：
import sys
class Unpickler(pickle.Unpickler):
def find_class(self, module, name):
'''This method gets called for every module pickle tries to load.'''
# python 2 --> 3 compatibility: __builtin__ has been renamed to builtins
if module == '__builtin__':
module = 'builtins'
# pandas compatibility: in newer versions, pandas.indexes has been moved to pandas.core.indexes
if 'pandas.indexes' in module:
module = module.replace('pandas.indexes', 'pandas.core.indexes')
__import__(module)
return getattr(sys.modules[module], name)
with open('/path/to/pickle.pkl', 'rb') as file:
pdf = Unpickler(file).load()
导入 pandas 没有抛出错误，而是试图读取一个选择的 pandas 数据帧：
import numpy as np
import pandas as pd
import matplotlib
import seaborn as sns
sns.set(style="white")
control_data = pd.read_pickle('null_report.pickle')
