Я хочу применить ALS с искрой в python, но когда я тренирую модель, возникает ошибка py4jjavaerror, версия java - 8, а версия python - 3.6, версия pyspark - 2.4.4
IЯ пробовал понизить Java, установить Java в Конде, изменить JAVA_HOME, но ни один из них не работает.
Вот мои данные:
+------+-------+------+
|userId|movieId|rating|
+------+-------+------+
| 1| 47| 3.5|
| 1| 50| 3.5|
| 1| 112| 3.5|
| 1| 151| 4.0|
+------+-------+------+
и коды:
als = ALS(userCol = 'userId', itemCol = 'movieId',ratingCol = 'rating',
rank = 2, maxIter = 15, regParam = 0.05,alpha = 40,
nonnegative = True, coldStartStrategy = 'drop',
implicitPrefs = False)
