Usando grafismos con PyCharm
Pasé casi 2 días navegando por Internet y no pude solucionar este problema. Estoy intentando instalar elpaquete de gráficos (Versión: 0.2.0-spark2.0-s_2.11) para ejecutar con spark a través de PyCharm, pero, a pesar de mis mejores esfuerzos, ha sido imposible.
He intentado casi todo. Por favor, sepa que he revisado este sitioaquí también antes de publicar una respuesta.
Aquí está el código que estoy tratando de ejecutar:
# IMPORT OTHER LIBS --------------------------------------------------------
import os
import sys
import pandas as pd
# IMPORT SPARK ------------------------------------------------------------------------------------#
# Path to Spark source folder
USER_FILE_PATH = "/Users/<username>"
SPARK_PATH = "/PycharmProjects/GenesAssociation"
SPARK_FILE = "/spark-2.0.0-bin-hadoop2.7"
SPARK_HOME = USER_FILE_PATH + SPARK_PATH + SPARK_FILE
os.environ['SPARK_HOME'] = SPARK_HOME
# Append pySpark to Python Path
sys.path.append(SPARK_HOME + "/python")
sys.path.append(SPARK_HOME + "/python" + "/lib/py4j-0.10.1-src.zip")
try:
from pyspark import SparkContext
from pyspark import SparkConf
from pyspark.sql import SQLContext
from pyspark.graphframes import GraphFrame
except ImportError as ex:
print "Can not import Spark Modules", ex
sys.exit(1)
# GLOBAL VARIABLES --------------------------------------------------------- -----------------------#
SC = SparkContext('local')
SQL_CONTEXT = SQLContext(SC)
# MAIN CODE ---------------------------------------------------------------------------------------#
if __name__ == "__main__":
# Main Path to CSV files
DATA_PATH = '/PycharmProjects/GenesAssociation/data/'
FILE_NAME = 'gene_gene_associations_50k.csv'
# LOAD DATA CSV USING PANDAS -----------------------------------------------------------------#
print "STEP 1: Loading Gene Nodes -------------------------------------------------------------"
# Read csv file and load as df
GENES = pd.read_csv(USER_FILE_PATH + DATA_PATH + FILE_NAME,
usecols=['OFFICIAL_SYMBOL_A'],
low_memory=True,
iterator=True,
chunksize=1000)
# Concatenate chunks into list & convert to dataFrame
GENES_DF = pd.DataFrame(pd.concat(list(GENES), ignore_index=True))
# Remove duplicates
GENES_DF_CLEAN = GENES_DF.drop_duplicates(keep='first')
# Name Columns
GENES_DF_CLEAN.columns = ['gene_id']
# Output dataFrame
print GENES_DF_CLEAN
# Create vertices
VERTICES = SQL_CONTEXT.createDataFrame(GENES_DF_CLEAN)
# Show some vertices
print VERTICES.take(5)
print "STEP 2: Loading Gene Edges -------------------------------------------------------------"
# Read csv file and load as df
EDGES = pd.read_csv(USER_FILE_PATH + DATA_PATH + FILE_NAME,
usecols=['OFFICIAL_SYMBOL_A', 'OFFICIAL_SYMBOL_B', 'EXPERIMENTAL_SYSTEM'],
low_memory=True,
iterator=True,
chunksize=1000)
# Concatenate chunks into list & convert to dataFrame
EDGES_DF = pd.DataFrame(pd.concat(list(EDGES), ignore_index=True))
# Name Columns
EDGES_DF.columns = ["src", "dst", "rel_type"]
# Output dataFrame
print EDGES_DF
# Create vertices
EDGES = SQL_CONTEXT.createDataFrame(EDGES_DF)
# Show some edges
print EDGES.take(5)
g = gf.GraphFrame(VERTICES, EDGES)
No hace falta decir que he intentado incluir el directorio de gráficos (miraaquí para entender lo que hice) en el directorio pyspark de spark. Pero parece que esto no es suficiente ... Cualquier otra cosa que he intentado ha fallado. Agradecería un poco de ayuda con esto. Puede ver a continuación el mensaje de error que recibo:
Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel).
