unable to access singlediodeparams or singlediode compute modules was created by caseyzak24

I am using the python SDK to try and run the

Code:

singlediode

and

Code:

singlediodeparams

modules. Below is my code (note that as far a I can tell it is all properly indented but I couldn't figure out how to display it correctly in this post):

Code:

irr_value_goal = list(range(25,1025,25))
singlediodecurve25 = {'irr':irr_value_goal,'Imp':[],'Vmp':[],'I_sc':[],'V_oc':[],'Pmp':[],'All_V':[],'All_I':[]}
ssc = PySSC()
# ssc.module_exec_set_print(0)
#create the data container where everthing gets carried around
data1 = ssc.data_create()
ssc.data_set_number(data1,b'alpha_isc',0.0007)
ssc.data_set_number(data1,b'adj_ref',-3.86179)
ssc.data_set_number(data1,b'a_ref',2.97911)
ssc.data_set_number(data1, b'Il_ref', 1.8409)
ssc.data_set_number(data1, b'Io_ref', 2.48981e-13)
ssc.data_set_number(data1, b'Rs_ref', 4.96815)
ssc.data_set_number(data1, b'Rsh_ref', 833.884)
ssc.data_set_number(data1, b'T', 25)
ssc.data_set_number(data1, b'I', 1000)
####RUN THE SIMULATION####
module = ssc.module_create(b'singlediodeparams')
if ssc.module_exec(module, data1) == 0:
    print('singlediodeparams simulation error')
    idx = 1
    msg = ssc.module_log(module, 0)
    while (msg != None):
        print('    : ' + msg.decode("utf - 8"))
        msg = ssc.module_log(module, idx)
        idx = idx + 1
    SystemExit( "Simulation Error" )
a = ssc.data_get_number(data1, b'a')
il = ssc.data_get_number(data1, b'il')
io = ssc.data_get_number(data1, b'io')
rs = ssc.data_get_number(data1, b'rs')
rsh = ssc.data_get_number(data1, b'rsh')

The output is simply:

Code:

singlediodeparams simulation error

Based on the fact that no additional info is provided with the error (not the case for other compute modules), it seems to me that the

Code:

singlediodeparams

string is not being recognized by the

Code:

module_create()

method call. I have even checked the ssc source code to ensure that these compute modules aren't referred to by different names. I also confirmed that the irradproc module works fine with the same setup/environment. These single diode modules work fine using the SDKtool on my machine. I am running OSX on a Mac laptop.

This is likely just a stupid coding error but any help is greatly appreciated.
