scipy.integrate.romberg has been deprecated since SciPy 1.12.0 and removed since SciPy 1.15.0, so running xpclr with SciPy >= 1.15 will lead to a error :
ImportError: cannot import name 'romberg' from 'scipy.integrate'
The version of scipy need to be specified explicitly since 2025:
conda install bioconda::xpclr scipy=1.14
