Hi
when i run infer.py, an error occurred. I had installed libtiff,
Traceback (most recent call last):
File "infer.py", line 7, in
from libtiff import TIFF
File "/home/miniconda3/envs/gwc_test/lib/python3.6/site-packages/libtiff/init.py", line 23, in
from .libtiff_ctypes import libtiff, TIFF, TIFF3D # noqa: F401
File "/home/miniconda3/envs/gwc_test/lib/python3.6/site-packages/libtiff/libtiff_ctypes.py", line 128, in
value = eval(value)
File "", line 1
