template full of NaN values causing the template gui to crash on start

I'm totally new to phy so maybe this is more of an issue with me not being familiar with the contents of the data files it needs to run, but I'm posting this here anyway in-case anyone else has this problem. I am using Kilosort2.5 to autosort my recording, but when I try to open the template-gui from the command line, I get this massive traceback (see the log file attached). I dropped a debugger into the line where the AssertionError is raised and it looks the template matrix passed to the _find_best_channel method in the io module is full of NaN values.

This is the command I executed from the command line:

cd <file path to my data files>
phy template-gui ./params.py

When I enter the debugger and check out the values of some of the variables in the scope of this method (NOTE: this assertion error is only raised after multiple successful calls to the _get_best_channel method):

786             amplitude = amplitude[order]
787             try:
788                 assert best_channel in channel_ids
789             except:
790                 import pdb; pdb.set_trace()
791  ->         assert amplitude.shape == (len(channel_ids),)
792             return channel_ids, amplitude, best_channel
793     
794         def _get_template_dense(self, template_id, channel_ids=None):
795             """Return data for one template."""
796             if not self.sparse_templates:

EDIT 1

So I compared the contents of my working directory with that of the example data provided on the repo and I noticed I do not have the channel_shanks.npy file in my working directory. Could this be the cause of my problems, and what information does this file contain?

EDIT 2

It seems this is a known issue: #1051; however, I tried the workarounds suggested toward the end of this thread and still no luck. Specifically, I tried setting the value for ops.minFR to 1 / 600 and the value for ops.nblocks to 0.
