Warning :Data:unable to set relative locations form 'mt_obj'

In making data input file , the warning statement " WARNING:Data: Unable to set relative locations from 'mt_obj' - not yet implemented" always exist. Does it afffect the projection results?

Expected Behavior

The Warning statment is to be fixed.

Current Behavior

D:\mtpywin\mtpy\mtpy\utils\calculator.py:371: RuntimeWarning: invalid value encountered in double_scalars z_rel_err = error/z_amp WARNING:Data: Unable to set relative locations from 'mt_obj' - not yet implemented WARNING:Data: Unable to set relative locations from 'mt_obj' - not yet implemented WARNING:Data: Unable to set relative locations from 'mt_obj' - not yet implemented WARNING:Data: Unable to set relative locations from 'mt_obj' - not yet implemented WARNING:Data: Unable to set relative locations from 'mt_obj' - not yet implemented WARNING:Data: Unable to set relative locations from 'mt_obj' - not yet implemented

Possible Solution

I did not install GDAL software. The pypoj is used to process coordinate projection problems.

np.savetxt(os.path.join(workdir,'center_position.txt'),

np.savetxt(os.path.join(workdir,'epsg.txt'),[do.model_epsg])
