SPI calculation is unsuccessful using climate_indices, while successful with SPEI package of R for same data

[usmansall]

while running the climate_indices python package for processing of spi, there is always a error as below. I tried with various datasets and also run the calculation using SPEI package of R and it worked successfully with the same data. Can you please figure out what the problem is? Thanks in advance.
