没有名为熊猫的模块。_libs.tslibs.frequencies

Question

我在这里和这里发现了关于同一问题的几个问题

from pyfinance.ols import PandasRollingOLS

我得到以下错误：

Traceback (most recent call last):
  File "/usr/local/lib/python3.8/site-packages/pyfinance/utils.py", line 78, in <module>
    from pandas.tseries.frequencies import FreqGroup, get_freq_code
ImportError: cannot import name 'FreqGroup' from 'pandas.tseries.frequencies' (/usr/local/lib/python3.8/site-packages/pandas/tseries/frequencies.py)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/local/lib/python3.8/site-packages/pyfinance/__init__.py", line 32, in <module>
    from .returns import TFrame, TSeries  # noqa
  File "/usr/local/lib/python3.8/site-packages/pyfinance/returns.py", line 42, in <module>
    from pyfinance import ols, utils
  File "/usr/local/lib/python3.8/site-packages/pyfinance/ols.py", line 15, in <module>
    from pyfinance import utils
  File "/usr/local/lib/python3.8/site-packages/pyfinance/utils.py", line 80, in <module>
    from pandas._libs.tslibs.frequencies import FreqGroup, get_freq_code
ModuleNotFoundError: No module named 'pandas._libs.tslibs.frequencies'

我尝试卸载和重新安装熊猫版本1.1.3, 1.1.2, 1.1.1和他们都不工作，我只是得到了同样的错误，然后我试图建立熊猫以下方式：

!python setup.py build_ext --inplace --force

我还是会犯同样的错误

Answer 1

确保您拥有正确版本的pyfinance。安装0.1.3解决了我的问题。

https://pypi.org/project/pyfinance/0.1.3/

Answer 2

仅供参考

我做了一些挖掘，看起来熊猫改变了他们的api，这导致了上面提到的错误。我修改了源代码，并在pyfinance/utils.py中包含了正确的导入：

第77行改为：

try:
    from pandas.tseries.frequencies import FreqGroup, get_freq_code
except ImportError:  # 0.24+, or somewhere around then
    from pandas._libs.tslibs.frequencies import FreqGroup, get_freq_code

到

try:
    from pandas.tseries.frequencies import FreqGroup, get_freq_code
except ImportError:
    from pandas._libs.tslibs.dtypes import FreqGroup
    from pandas.tests.tslibs.test_period_asfreq import get_freq_code
