Problem with OilLibrary

[lindbergh153]

Hello developers, sorry to bother you. I tried to input the oil substance by using the OilLibrary package and failed. The error message is attached as follows.

 -->Loading NOAA Oil Library Oil:  AD00709

When I run the command to import this oil, I do not get this error. For example:

from tamoc import dbm_utilities as dbm_utils oil = dbm_utils.get_oil('AD00709', 20000., 2000.)

works fine. Did you use similar syntax? If you are using blowout.Blowout object, it should follow this syntax. If you continue getting an error, it may have to do with your ADIOS installation. Do all of the tests pass for Adios?

Thanks, Scott

Thanks for your reply. I ran the code recommended and the error information is attached below. I guess something wrong with the installation.

from tamoc import dbm_utilities as dbm_utils oil = dbm_utils.get_oil('AD00709', 20000., 2000.)

Guessing here, but I think the specific issue is that the vapor_pressure method uses an lru_cache.

and the lru_cache requires that the parameters be "hashable", which and oil_props object is not.

However, this has indeed worked in the past, so I think the issue here is that the lru_cache syem is different in some wy depending on Python version, etc.

OilLibrary is best tested with Python 3.8 (and py2.7, bu that's dead now) -- so if TAMOC is py38 compatible, I'd go with that verson and see if you can get it to work.

If not -post an issue on the OilLibary projects as we'll see what we can do:

NOTE: I looked yesterday, and realized I hadn't pushed the latest version to gitHub. I've now done that, so please get the latest OilLibrary code and try again.

I updated the package and the same issue occurred as follows. The python version I used is 3.76.

from tamoc import dbm_utilities as dbm_utils oil = dbm_utils.get_oil('AD00709', 20000., 2000.)

Try Python 3.8 -- that may be the issue.
