running Python, ADF_d error

[rudmac]

After:
make USE_OPENMP=1 USE_BLAZE=1 USE_BLAS=1
python setup.py build_ext --inplace --force
...

adf.csv is saved from Example2.cpp

Example2.cpp
...
urt::Vector<double> data = urt::wiener_process<double>(nobs);
urt::WriteToCSV("adf.csv", data);
...

Python code:

adf = pd.read_csv('adf.csv', sep=',', header=None)
test = urt.ADF_d(adf[0].values, lags=10, trend='ct')
test.show()

Result is:
