• h5py problem about rsmas_insar

Hi Falk:

I met a problem about h5py with I run process_rsmas.py. I listed the error as following:

File "/home/user/utility/anaconda3/lib/python3.7/site-packages/h5py/init.py", line 26, in from . import _errors ImportError: libhdf5.so.101: cannot open shared object file: No such file or directory

I uninstalled h5py and reinstalled h5py using conda, but the error was still there. Could you please tell me how to fix the problem?

Solution: Hi Chou, I never saw this. You may have something else in your Conda environment which causes conflicts. I see that you are installing in an area different than suggested in our setup. Falk

Actually, in GuizhouSenDT164.template,

topsStack.boundingBox = '27.12 27.87 103.7 106.0'

Solution: boundingBox is not correct
