Interattivo Multi-Filtrabili Dash Plotly Mappa GIS-- Figura Non funziona

Ciao Stack Exchange,

Per la vita di me non riesco a capire che cosa sto facendo di sbagliato, a questo punto. Io sono un programmatore principiante quindi sono orgoglioso di essere qui; tuttavia, se ci sono altre soluzioni più efficaci per favore, sentitevi liberi di suggerire.

File Di Dati:

• gdf_final_serial
• ^Questa è una versione ridotta come l'attuale set di dati è ~680K Righe
• geo_school
• ^Json essere utilizzato

Che cosa ho bisogno di Dash app per fare:

• Lavoro come un Multi-Filtrabili Mappa GIS con riferimento a campi elencati (Contea, Distretto Nome, l'Età, il RE, Quartili, Custodia Insicuro)
• In base ai filtri scelto, aggiornare il px.choropleth_mapbox con un conteggio accurato dei 'punti'.

Facciamo un salto nel codice. Anche io sono in esecuzione su un Google Colab Notebook.

filename_1 = root_path+"schoolDistrictBoundaries_Fixed.json"
file = open(filename_1)
schoolDistricts = gpd.read_file(file)

###   Creating gdf_final_serial

geo_df = gpd.GeoDataFrame.from_features(geo_school["features"]).merge(joined, on="OBJECTID").set_index("OBJECTID") #GeoJson Join to Joined Dataframe
cleaned_geo_df = geo_df[["geometry_x", "CountyName_x", "RE", "QUARTILES", "HOUSING_INSECURE", "County", "Age", "DistrictName_x"]] #Picks the right columns
geo_df_final = cleaned_geo_df.rename(columns={"CountyName_x": "CountyName", "geometry_x": "geometry", 'DistrictName_x': 'DistrictName'}) #Changing Column Names
geo_df_final.to_pickle(root_path+"geo_df_final") #Write to drive as a pickle to serialize
df_final_serial = pd.read_pickle(root_path+"geo_df_final") #Read as DataFrame
gdf_final_serial = gpd.GeoDataFrame(data = df_final_serial, geometry= "geometry", crs = "epsg:4326") #Turn into GeoPandas DataFrame and set the geometry and crs


re_indicators = gdf_final_serial.RE.unique()

Sono stato in grado di ricevere diverse condizioni in cui la mappa/filtro produrre una singola contea, a volte due contee-ma non tutta la shebang. Tenete a mente il mio obiettivo finale è quello di creare questo per l' INTERO set di dati (magari utilizzando RapidsAI da NVIDIA; tuttavia sto avendo problemi con l'installazione che anche all'interno di Google Colab).

La cosa più interessante è che quando eseguo questo codice al di fuori del cruscotto (come un campione dell'effettivo dataset) e passare alla fig.show(), verrà visualizzata; tuttavia, non funzionerà nel Cruscotto app.

Ho il sospetto che il problema è con il mio json gestione o la finale di callback come debugger indica che, mentre gli ingressi sono lì, my_map.la figura non è l'output di dati. Apprezzo l'aiuto.
