## What changes were proposed in this pull request? Due to [API change](https://github.com/numpy/numpy/pull/4257/files#diff-c39521d89f7e61d6c0c445d93b62f7dc) at 1.9, PySpark image doesn't work with numpy version prior to 1.9. When running image test with numpy version prior to 1.9, we can see error: ``` test_read_images (pyspark.ml.tests.test_image.ImageReaderTest) ... ERROR test_read_images_multiple_times (pyspark.ml.tests.test_image.ImageReaderTest2) ... ok ====================================================================== ERROR: test_read_images (pyspark.ml.tests.test_image.ImageReaderTest) ---------------------------------------------------------------------- Traceback (most recent call last): File "/Users/viirya/docker_tmp/repos/spark-1/python/pyspark/ml/tests/test_image.py", line 36, in test_read_images self.assertEqual(ImageSchema.toImage(array, origin=first_row[0]), first_row) File "/Users/viirya/docker_tmp/repos/spark-1/python/pyspark/ml/image.py", line 193, in toImage data = bytearray(array.astype(dtype=np.uint8).ravel().tobytes()) AttributeError: 'numpy.ndarray' object has no attribute 'tobytes' ---------------------------------------------------------------------- Ran 2 tests in 29.040s FAILED (errors=1) ``` ## How was this patch tested? Manually test with numpy version prior and after 1.9. Closes #23484 from viirya/fix-pyspark-image. Authored-by: Liang-Chi Hsieh <viirya@gmail.com> Signed-off-by: Hyukjin Kwon <gurwls223@apache.org> |

Apache Spark
Spark is a fast and general cluster computing system for Big Data. It provides high-level APIs in Scala, Java, Python, and R, and an optimized engine that supports general computation graphs for data analysis. It also supports a rich set of higher-level tools including Spark SQL for SQL and DataFrames, MLlib for machine learning, GraphX for graph processing, and Spark Streaming for stream processing.
Online Documentation
You can find the latest Spark documentation, including a programming guide, on the project web page
Python Packaging
This README file only contains basic information related to pip installed PySpark. This packaging is currently experimental and may change in future versions (although we will do our best to keep compatibility). Using PySpark requires the Spark JARs, and if you are building this from source please see the builder instructions at "Building Spark".
The Python packaging for Spark is not intended to replace all of the other use cases. This Python packaged version of Spark is suitable for interacting with an existing cluster (be it Spark standalone, YARN, or Mesos) - but does not contain the tools required to set up your own standalone Spark cluster. You can download the full version of Spark from the Apache Spark downloads page.
NOTE: If you are using this with a Spark standalone cluster you must ensure that the version (including minor version) matches or you may experience odd errors.
Python Requirements
At its core PySpark depends on Py4J (currently version 0.10.8.1), but some additional sub-packages have their own extra requirements for some features (including numpy, pandas, and pyarrow).
