Python 3.6 not supported?

from copulae.

Ah.. the issue is not copulae. As you can see, the 3.6 wheel for copulae exists. The issue is that scipy stopped supporting 3.6 since their 1.6 release.

One way to solve this is to install scipy first. Then install copulae.

from copulae.

Thanks for your response, I managed to install copulae with that method but getting unexpected errors now, perhaps due to my current module versions?

Does this example code still work?

from copulae.datasets import load_residuals, load_marginal_data
from copulae import GaussianCopula, StudentCopula

residuals = load_residuals()
residuals.head()

_, ndim = residuals.shape
g_cop = GaussianCopula(dim=ndim)  # initializing the copula
g_cop.fit(residuals)

I am getting a ValueError like below:

 File "<ipython-input-54-d2563863>", line 9, in <module>
    g_cop.fit(residuals)
  File "/users/is/npr/pyenvs/search/lib/python3.6/site-packages/copulae/copula/base.py", line 134, in fit
    elif np.any((data < 0) | (data > 1)):

    .format(self.__class__.__name__))
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

I did the following and it worked okay

conda create -n py36 python=3.6 copulae
conda activate py36
python

from copulae.datasets import load_residuals, load_marginal_data
from copulae import GaussianCopula, StudentCopula

residuals = load_residuals()
residuals.head()

_, ndim = residuals.shape
g_cop = GaussianCopula(dim=ndim)  # initializing the copula
g_cop.fit(residuals)

from copulae.

It looks like an error raised by pandas. Try getting your packages up to requirements first

requirements = [
    'numpy >=1.19',
    'pandas >=1.1',
    'scikit-learn >=0.23',
    'scipy >=1.5',
    'statsmodels >=0.12.1',
    "typing-extensions >=3.7.4.3; python_version < '3.8'",
    "wheel >=0.36",
    'wrapt >=1.12'
]
