QUESTION
I want to train a VGG16 model with Horovod PyTorch on 4 GPUs. Instead of using the CIFAR10 dataset of torch vision.datasets.CIFAR10, I would like to split the dataset on my own. So I downloaded the dataset from the official website and split the dataset. This is how I split the data:
...ANSWER
Answered 2020-Nov-10 at 11:25Maybe it is because I did not normalize the dataset. Thanks for everyone's help!
QUESTION
Right now, I am using Horovod to run distributed training of my pytorch models. I would like to start using hydra config for the --multirun feature and enqueue all jobs with SLURM. I know there is the Submitid plugin. But I am not sure, how would the whole pipeline work with Horovod. Right now, my command for training looks as follows:
...ANSWER
Answered 2020-Sep-28 at 16:38The Submitit plugin does support GPU allocation, but I am not familiar with Horovod and have no idea if this can work in conjunction with it. One new feature of Hydra 1.0 is the ability to set or copy environment variables from the launching process. This might come in handy in case Horovod is trying to set some environment variables. See the docs for info about it.
QUESTION
I'm very new to Apache Spark. Before I was experimenting with Dask
, Ray
, and Horovod
which can easily create GPU clusters.
I'm currently using Apache Spark 3.0
(which added NVIDIA GPU support) but having trouble with creating GPU clusters.
I attemped to configure the spark-defaults.conf
as follows:

Answered 2020-Jul-23 at 16:10After reviewing several hidden websites, I compiled the instructions to setting up the GPU cluster in Apache Spark 3.0 in the following blog: http://deeplearningyogi.com/ Please comment.

QUESTION
I have written an Apache Spark DataFrame as a parquet file for a deep learning application in a Python environment ; I am currently experiencing issues in implementing basic examples of both petastorm (following this notebook) and horovod frameworks, in reading the aforementioned file namely. The DataFrame has the following type : DataFrame[features: array, next: int, weight: int]
(much like in DataBricks' notebook, I had features
be a VectorUDT, which I converted to an array).
In both cases, Apache Arrow throws an ArrowIOError : Invalid parquet file. Corrupt footer.
error.
I discovered in this question and in this PR that as of version 2.0, Spark doesn't write _metadata
or _common_metadata
files, unless spark.hadoop.parquet.enable.summary-metadata
is set to true
in Spark's configuration ; those files are indeed missing.
I thus tried rewriting my DataFrame with this environment, still no _common_metadata
file. What also works is to explicitely pass a schema to petastorm when constructing a reader (passing schema_fields
to make_batch_reader
for instance ; which is a problem with horovod as there is no such parameter in horovod.spark.keras.KerasEstimator
's constructor).
How would I be able, if at all possible, to either make Spark output those files, or in Arrow to infer the schema, just like Spark seems to be doing ?
Minimal example with horovod ...ANSWER
Answered 2020-Apr-29 at 13:40The problem is solved in pyarrow 0.14+ (issues.apache.org/jira/browse/ARROW-4723), be sure to install the updated version with pip (up until Databricks Runtime 6.5, the included version is 0.13).
Thanks to @joris' comment for pointing this out.

Install horovod
You can use horovod like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
