Hi,
Many thanks for making this clustering package available!
I have a windows machine with Python 3.6.5, numpy 1.19.5, scipy 1.5.4, scikit-learn 0.24.2
I did a manual installation by running command "python setup.py install". It went OK and then, I tried to test the installation following Python code in one of examples:
data_F1= pd.read_csv('Fig1.dat', sep=" ", header= None)
est= DPA.DensityPeakAdvanced(Z= 1.5)
est.fit(data_F1)
The last line produced the following error message:
Traceback (most recent call last):
File "", line 1, in
File "C:\Temp\Python\Python3.6.5\lib\site-packages\dpapipeline-0.0.2-py3.6-win-amd64.egg\Pipeline\DPA.py", line 400, in fit

ValueError: Buffer dtype mismatch, expected 'long' but got 'long long'
Thanks for your help,

Thanks for posting the bug error! I will provide an update shortly.
Hi. The problem was that the long type in the Cython codes are long for Linux, but long long for Windows. I have replaced them with int64_t (see commits above for more details). Those changes should solve the issue, could you give it a try?
Hi @mariaderrico ,
Many thanks for fixing the reported issue. I will give a try as soon as possible, and let you know.

I downloaded the zip file and manually installed the package. Run the same Python code and it worked fine.
I noticed the following warnings during the installation:
