demo does not work in pyCharm

Inizia con la demo in tensor_frame_test.py e segui tfs.block attraverso tensorframes/core.py, in particolare _auto_placeholder e _java_api. Verifica come viene caricato il file tensorframes-0.2.3-s_2.10.jar fornito e analizza la classe mancante org.tensorframes.impl.DebugRowOps segnalata. Il lavoro è completato quando la demo raggiunge df2.collect() senza la ClassNotFoundException.

i'm currently trying to run the demo in pyCharm my file looks like this:
the attached pyFile is the location of my tensorframes jar

import tensorflow as tf
from pyspark.sql import Row
from pyspark.sql import SparkSession

spark = SparkSession
.builder
.appName("PythonSQL")
.getOrCreate()

spark.sparkContext.addPyFile('/home/hdiuser/PycharmProjects/TensorFramesTest/tensorframes-0.2.3-s_2.10.jar')
import tensorframes as tfs

data = [Row(x=float(x)) for x in range(10)]
df = spark.createDataFrame(data)
print df.show()
with tf.Graph().as_default() as g:
#The TensorFlow placeholder that corresponds to column 'x'.
#The shape of the placeholder is automatically inferred from the DataFrame.
x = tfs.block(df, "x")
# The output that adds 3 to x
z = tf.add(x, 3, name='z')
# The resulting dataframe
df2 = tfs.map_blocks(z, df)

The transform is lazy as for most DataFrame operations. This will trigger it:

df2.collect()

the output is as follows:

| x|
+---+
|0.0|
|1.0|
|2.0|
|3.0|
|4.0|
|5.0|
|6.0|
|7.0|
|8.0|
|9.0|
+---+

None
