Error message in python 3 object has no attribute 'min_data'

Question

I am new to python and I wondered if anyone could interpret what this error message means for me? I am trying to run lead 210 data using PyPlum https://github.com/maquinolopez/PyPlum/blob/PyPlum/README.md

I have downloaded all of the requirements using either conda install -c conda-forge or sudo easy_install and I am using miniconda. There definitely is data in the folder so I am not sure what it is telling me?

Thanks

My code is as follows:

conda activate my-py

   cd pytwalk-1.5

   sudo python3 setup.py install

   cd /Users/sophiewilliams/PyPlum

   python3

---

   import PyPlum as Plum

   BB = Plum.Plum("BB")

   BB.runPlum()

That should run the model however I am getting the error:

BB = Plum.Plum("BB")>>> BB = Plum.Plum("BB")

Answer 1

I checked this source file and it seems that the Plum object had not loaded some 14C data to self.min_data in the load_data method.

Make sure that you have a ~/Documents/PyPlum/BB/BB-C.csv file containing the 14C data. (I have no idea what that is..)
