TypeError: Mismatch between array dtype ('object') and format specifier ('%.18e')

When I use dpgen, I get an error at the last step of 02.fp

nohup: ignoring input
Traceback (most recent call last):
File "/public1/home/scfa8472/anaconda3/lib/python3.11/site-packages/numpy/lib/npyio.py", line 1623, in savetxt
v = format % tuple(row) + newline
~~~~~~~^~~~~~~~~~~~
TypeError: must be real number, not NoneType

The above exception was the direct cause of the following exception:
