Cant start training by following instructions from docs

[lzivadinovic]

Hi!
I'm trying to use this code by running provided examples from documentation. First problem was that url that is hardcoded here was invalid github link, and that variable should be changed to something like this

_example_data_url = "https://raw.githubusercontent.com/djones1040/SALTShaker/main/examples/saltshaker-latest-training.tgz"

After downloading training data and unpacking it, when i run trainsalt -c traingradient.conf from provided file, it says it cant find kcor/*fits files. Even if configuration in traingradient.conf file uses relative paths to kcor files, it looks its always appended to init_rootdir variable, here is full error for this command

During handling of the above exception, another exception occurred:

It looks like it's requiring data to be in site-packages where lib is actually installed, not in random directory that you want to use. Is there workaround for this or should i just copy data there and run training from that location?
