unable to open message file #4

Closed mengfeimu closed 6 years ago

mengfeimu commented 6 years ago

It seems WDMUtil runs into some problems. When I run examples/test/test01.py, the error shows:

unable to open message file

I copied hspfmsg.wdm to another folder, but it didn't work. Do you have any idea what's the reason behind this? By the way, I installed the pyhspf 0.2.4 from PyPI few days ago. Thanks!

I temporally solved this problem by set messagepath to the hspfmsg.wdm in BASINS software folder:

messagepath = 'C:/BASINS41/bin/Plugins/BASINS/hspfmsg.wdm'
wdm = WDMUtil(verbose = True, messagepath = messagepath)

I tried to copy BASINS/hspfmsg.wdm into pyhspf/core/ and replace the original hspfmsg.wdm, but it didn't work.

This is a temporal solution for the problem. Hope anyone can find the reason behind the problem.

I use SARA Time Series Utility for all WMD related tasks. WDMUtil is not supported anymore.

The problem is not the message file in the core directory, but is usually related to the length of the absolute path exceeding 64 characters, which is hard-coded into the program. We have added some documentation to help point this out. You can work around the limit by providing the path the hspfmsf.wdm. I would use the version that exists with this build of hspf.
