Problem when importing #71

Closed DIUANA closed 4 years ago

DIUANA commented 4 years ago

Hi I am trying to use gdxpds in an python 3.4.5 environment however when I try to import I get the following error: 

raise ValueError('_names_ are reserved for future Enum use')

ValueError: names are reserved for future Enum use

I tried to uninstall enum34 and it did not work, it did not work with enum34 installed either.

Have you faced this before? Is there any way to work around this?

Thanks in advance.

I found a way to work around this. I installed a previous version of gdxpds, however now it is Unable to locate my GAMS directory (I am having this issue using windows 10, and the gams directory is defined in the path system variable) I am trying this:

from gams import *
gw = GamsWorkspace()
print(gw.system_directory)
gams_dir = gw.system_directory
sys.path.append(gams_dir)
gdxpds.load_gdxcc(gams_dir)

Even though when I run this line: dfg = gdxpds.to_dataframes(gdx_file)

I got:

dfg = gdxpds.to_dataframes(gdx_file)
Traceback (most recent call last):

File "", line 1, in
dfg = gdxpds.to_dataframes(gdx_file)

raise RuntimeError("Unable to locate your GAMS directory.")

gdxpds doesn't read PATH yet, there is an MR which fixes this https://github.com/NREL/gdx-pandas/pull/69 but that's waiting for review.

Alternatively, if you put the gams directory in the sytem variable GAMS_DIR that might work.

Closing after today's changes to the gams directory finder
