How do i properly point rhino to an existing Anaconda env?

@eirannejad
Thanks for helping me set-up conda in Rhino/Gh.
Some issues/ suggestions:

  1. Script Editor in Gh randomly get’s locked and I have to reset python 3 runtime > restart Rhino > open script editor in Rhino8 > run some script > then open Script editor in gh and sometimes it starts working again.

  2. It would be awesome to have a dataframe datatype hint here.

  3. My current workaround for item 2 above is to convert a dataframe into list of lists and graft it to get individual columns, but it exports system object instead of data. Not sure how to get around this? any suggestions?

def dataframe_to_list_of_lists(df):
    list_of_lists = []
    # First sublist: Column names
    column_names = df.columns.tolist()
    list_of_lists.append(column_names)
    # Subsequent sublists: Column data
    for col in column_names:
        column_data = df[col].tolist()
        list_of_lists.append(column_data)
    return list_of_lists

df_Joint_Coordinates, ret = get_sap_table('Joint Coordinates')
list_Joint_Coordinates = dataframe_to_list_of_lists(df_Joint_Coordinates)
list_Joint_Coordinates_0 = list_Joint_Coordinates[0]

I think 2 and 3 need a .Net implementation of a Dataframe, or even native support for Pandas in Grasshopper.

@Aditya_Kaushik

Which component is the receiver of the dataframe type? Another Python 3 component or other Grasshopper components?

I am assuming you are referencing pandas.DataFrame right? If that is the case, that type is only known to Python 3 components and you’d need to convert that to a dotnet data structure to be passed to other components.

If the receiver is also a Python 3 component, you can turn off the output marshalling from the advanced context menu (Shift + Right Click)

This way the output data structure goes directly into the receiver Python 3 component (make sure to turn off input marshalling on the receiver component as well)

Is this relevant to output data frame as a data tree?

28

No this is related to being able to pass Python object type to a Generic dotnet type like Grasshopper’s DataTree instead of having to use System.Object. So both these statements work now:

DataTree[object]
DataTree[System.Object]

It would be great if any of you having problem installing and importing numpy would be able to check this:
