我在Win7 64，Anaconda Python安装，pip安装了PyDEM。
我在.calc_slopes_directions()个实例上调用DEMProcessor时遇到错误（见下文）。
我知道this question;这似乎与我的问题不一样。
此LoweringError: slc0.8似乎与Numba有关。
这是我输入的代码和我得到的错误：
from pydem.dem_processing import DEMProcessor
os.chdir(r'D:\my_path')
a_tile = r'31an2_clipped_wgs84.tif'
dem_proc = DEMProcessor(a_tile)
mag, aspect = dem_proc.calc_slopes_directions()
starting slope/direction calculation for chunk 1 [0:516, 0:516]
