What the input data would be like?

[godk0509]

Is the data the value of Probability density function ,or the value of random variable？

Did you have any success? I am trying to fit empirical return data with this package, but I keep getting array has an inhomogeneous shape error

The data input into Gaussian copuls is a 1696×2 array array, and the variable name is cdf_data,
model_gaussian = GaussianCopula(dim=2)
model_gaussian.fit(cdf_data, method="cmle")
fitted_gumbel_r = model_gaussian.get_corr()

but I keep getting errorarray has an inhomogeneous shape.
File "G:\Anaconda3\envs\py39_copula\lib\site-packages\pycopula\copula.py", line 614, in log_likelihood
RInv = 1. / RDet * np.asarray([[ S[1, 1], -rho], [ -rho, S[0, 0] ]])
ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 2 dimensions. The detected shape was (2, 2) + inhomogeneous part.
