Hello,
I am trying TFoS, and successfully converted the MNIST zip files into HDFS files following the link here. However, when I try to run the sample named "Run distributed MNIST training (using feed_dict)", I encountered the following error saying "KeyError: 'input' error" and I have no clue on what's going on.
My environment is:
Spark 2.1.1 + YARN/Hadoop 2.6 + latest TFoS (master branch) + latest TF (1.2.0). I am using YARN-client mode. Below is the command line I am using. I have a small cluster of 2 nodes (I remember some issue mentioned that the executor number should be better be set to the cluster node number, not quite sure though) and I am sure that libhdfs.so and libjvm.so is in the LD_LIBRARY_PATH.
Also I did a bit research and found a similar issue #32 with a couple of other issues - However since that issue was on Feb, I thought all the fixes should be merged in the latest branches. That's why I am raising this issue again.
I am also attaching the full logs Untitled-1.txt in case you need more information.
Thanks for looking at it!

1.the data is MATLAB 5.0 MAT-file.
according the https://github.com/yahoo/TensorFlowOnSpark/wiki/Conversion,I change the code.
but on condition that the data is valid for tensorflowOnSpark to use on HDFS.
2.Need I change the data to TFRecords?
hello:
from the issues,i find some peole both has the question,like
AttributeError: 'NoneType' object has no attribute 'get'.
in my case no yarn ,i find may be like this:
when the container die(kill by nm),the ppid is not the same to cluster_info which return reserve methon.
so through cluster_info some container is not exit, can't get the state.
Hi,
I ran the CIFAR-10 example on a 2 node stand-alone Spark cluster, both nodes have a single GPU. What I expected to see, was that running with both nodes would be faster than running on a single node. What I'm seeing instead is no scaling at all. The node with the fastest GPU finishes first, sitting idle until the other node also finishes (I'm looking at: watch -n1 nvidia-smi).
Also, when training on a single node, the faster GPU is barely performing better (bottleneck?).
Here are some more details:
Command to run with both nodes:

Am I running the example wrong? What I want is to just see any example of training a model where training time decreases when running on more nodes.
I append some code in mnist_dist.py file, like this:
while not sv.should_stop() and step < args.steps:
# Run a training step asynchronously.
# See `tf.train.SyncReplicasOptimizer` for additional details on how to
# perform *synchronous* training.
# using feed_dict

feed = {x: batch_xs, y_: batch_ys}
if len(batch_xs) != batch_size:
print("done feeding")
break
else:
if args.mode == "train":
_, step = sess.run([train_op, global_step], feed_dict=feed)
# print accuracy and save model checkpoint to HDFS every 100 steps
if (step % 100 == 0):
print("{0} step: {1} accuracy: {2}".format(datetime.now().isoformat(), step,
sess.run(accuracy,
{x: batch_xs, y_: batch_ys})))
else: # args.mode == "inference"
labels, preds, acc = sess.run([label, prediction, accuracy], feed_dict=feed)
results = ["{0} Label: {1}, Prediction: {2}".format(datetime.now().isoformat(), l, p) for
l, p in zip(labels, preds)]

how can i make the task work well on exporting model. BTW, this export model code can work well on tensorflow distribution. thanks a lot
There is a problem occurs when run the following lines in TFSparkNode.py
:
# assign TF job/task based on provided cluster_spec template (or use default/null values)
job_name = 'default'
task_index = -1
for jobtype in cluster_spec:
nodes = cluster_spec[jobtype]
if worker_num in nodes:
job_name = jobtype
task_index = nodes.index(worker_num)
break;
Assume that I have a cluster which includes 5 spark workers - 1 non-GPU worker and 4 GPUs worker. I need the non-gpu worker is to run a ps
tensorflow job but Spark can allocate it to a GPUs worker. So, this make a worker
tensorflow job will run on the non-GPU worker.
I want to ask if This version is 100% compatible with Tensorflow 1.1.0 and Keras 2.0 (specially with CNNs)?
If not not what should i consider when training/running such model in hadoop?
Thank you for open-sourcing this project. Great work!

Thanks for your efforts in developing TensorFlowOnSpark and making it opensource. I have two doubts regarding this new confluence of 2 most popular paradigms:-
Would my cluster work if have only Spark and Tensorflow without Hadoop?
How does the cluster behave if one of the node fails? Would the whole operation fail or is the cluster fault-tolerant?
Since Keras can use Tensorflow as the backend, how can one use TensorFlowOnSpark with Keras if it is possible at all? Thank you.
The documentation for MNIST EC2 example states that we can set the NUM_GPU
environment variable to specify how many GPUs we want to be used per node. Is the same true for Hadoop based YARN clusters as well?
hello, thank you for your work to open tensorflow on spark.

Hi,
I've tried the solution on a Spark enabled Yarn cluster (CPU only). I noticed that it requires very high executor memory. For the mnist example, the actual model is very small, but I need to specify around 27GB executor memory to get it running using 10 executors. The amount of required memory increases when I tried a larger dataset.
Could someone explain a bit why it requires so much memory to run on spark? Is it related to the message exchange among ps and workers as in tensorflow/tensorflow#6508 ?
Thank you very much for the help!
Yiming.

Thanks for this great project, really meets a lot of unmet needs.
Is there a roadmap for when TFoS will be compatible with Tensorflow 1.0. There is now support for a new ClusterManager for CloudML and Mesos. Could this project attempt to get into tensorflow/contrib as a Yarn alternative?

I do not why .it blocked there
I am trying to run a the multi-GPU CIFAR example on YARN cluster with InfiniBand. I have followed the instructions as provided in the instruction. I execute CNN on Spark using the following command:
export NUM_GPU=2
export MEMORY=$((NUM_GPU * 11))
${SPARK_HOME}/bin/spark-submit \
--master yarn \
--deploy-mode cluster \
--num-executors 3 \
--executor-memory ${MEMORY}G \

I have NVIDIA Tesla K80 GPUs installed on each node. Each node has two GPUs per node and each GPU has approximately 11GB of memory and that is how I am calculating the memory proxy for GPUs for YARN.
In order to check how much (if it all) of the GPUs or utilized on each node I run the nvidia-smi
command but surprisingly none of the nodes show any GPU process running. The output of this command on one of the NodeManger is:

When I run ps aux
I see the relevant Python daemons running on each of the NodeManger nodes. The top
command also shows Python consuming quite a lot of CPU cycles.

What do you guys think is happening here? Would really appreciate any help.
I am trying to run the TensorFlowOnSpark example using Hadoop cluster on GPUs. I was able to configure the environment correctly, but when it comes to the point of Convert the MNIST zip files into HDFS files and I run the spark-submit job given in the example I get the following error:
py4j.protocol.Py4JJavaError: An error occurred while calling None.org.apache.spark.api.java.JavaSparkContext.

I am assuming I have to setup a yarn queue for it to able to utilize GPUs. If that is the case, how do I do it ?
Any help would be really appreciated.
Environment:
CUDA: 8
CUDNN: 5.0
Python: 2.7.3
Tensorflow: 1.0
I put the spark/mnist_spark.py file onto the jupyter notebook for running. But there is a weird error "An error occurred while calling z:org.apache.spark.api.python.PythonRDD.collectAndServe." What's the meaning of this error message?
The jupyter notebook starts with ipython shell. I import pyspark and input the configuration by using pyspark.SparkConf(). There is no problem to create the TFcluster. But when it came to cluster.train, it crashed and popped out the error message. The following is my running code and result. Thank you for helping!

Specifically, how to generate ~/y/lib64 ?
Any suggestions will be appreciated!

Hi,
I ran the imagenet example on a 2 node stand-alone Spark cluster, both nodes have a single GPU.
GPU utilization is not what I was hoping for. On one node it's constantly between 4% and 8%, this node also has suspiciously little information in it's log file. It ends with "Started server with target: grpc://localhost:42158".
On the other node utilization sometimes jumps to higher values for like a fraction of a second, up to about 85% (I'm looking at: watch -n1 nvidia-smi).
Also, it seems only one node is writing to /tmp/imagenet_distributed_train_model, the one with the higher utilization.

I'm trying to implement a synchronous distributed Recurrent Neural Network using TensorFlow on multiple servers. Here's the link to my code: https://github.com/tushar00jain/spark-ml/blob/master/rnn-sync.ipynb. I've also provided the relevant part below.
I want the computations within the same batch to happen in parallel but I think it's still computing separate RNNs on each worker server and updating the parameters on the parameter server separately. I know this because I am printing the _current_state variable after I run the graph for each batch. Also, the _total_loss for the same global step is different on each worker server.
I'm following the instructions provided at the following links: https://www.tensorflow.org/deploy/distributed#replicated_training https://www.tensorflow.org/api_docs/python/tf/train/SyncReplicasOptimizer
Is this a bug or is there something wrong with my code?

After I deployed the spark-2.2.0, failed to run the script of the mnist example.
The script is the GetStarted_YARN . See the script detail at the following.
It is OK un the spark 2.1.1 , but it is failure on spark-2.2.0 .
Thanks for you help!
The error is : /home/xxx/Python/bin/python not found.

Hello,
I'm trying to follow the steps on "GetStarted_YARN" to set up TensorFlowOnSpark on AWS EMR (master:c3.2xlarge, core:m3.xlarge). My small cluster is EMR-5.5.0.
I was not able to get through "pip install pydoop". I've tried manually setting "JAVA_HOME" and "HADOOP_HOME" and troubleshooting pydoop without success. It seemed that pydoop was missing the expected the env like "HADOOP_HOME", "HADOOP_VERSION" and etc, and that solving one issue leads to another. For the very first step, it is discouraging. Am I on the wrong path? What am I missing? Thanks ahead very much!
I am trying to run the MNIST example on a YARN cluster. I am using the following command to generate save images and labels as TFRecords but I get the following error.

Moreover I also extracted the jar to confirm if it contains the concerned class and it does. What could be the problem?
Environment:

I am using TF 1.2 and Spark 2.0.2 with the pip install version of TFoS.
The command I used is this one:

I see from some workers that the supervisor gets shutdown probably because of the # of epochs has been reached.

This however does seem like a race condition somewhere because this works some times, and others it just hangs. @leewyang any idea on where to start looking at please?
I have setup MNIST example on a hadoop 2.6 server with spark 1.6.1. I have been trying to train it using the following command,
${SPARK_HOME}/bin/spark-submit \
--master yarn \
--deploy-mode cluster \
--queue default \
--num-executors 4 \
--executor-memory 20G \
--py-files TensorFlowOnSpark/tfspark.zip,TensorFlowOnSpark/examples/mnist/spark/mnist_dist.py \
--conf spark.dynamicAllocation.enabled=false \
--conf spark.yarn.maxAppAttempts=1 \
--conf spark.executor.cores=1 \
--archives hdfs:///user/${USER}/Python.zip#Python \
--conf spark.executorEnv.LD_LIBRARY_PATH="$JAVA_HOME/jre/lib/amd64/server:/usr/lib/hadoop2.6/lib/native/" \
TensorFlowOnSpark/examples/mnist/spark/mnist_spark.py \
--images mnist/csv/train/images \
--labels mnist/csv/train/labels \
--mode train \
--model mnist_model
But the excecution hangs.
A few things I found out while trying to debug it,
logdir = None
works as suggested in #33. Solutions suggested in the same issue to modify the model directory location to not work. Moreover, logs suggest that the correct URL is picked by the executors anyway.Logs can be viewed at,

Good morning,
I am following the guide to install TFoS on Hadoop Cluster. At first point it is necessary install Python 2.7. Is possible to do it with Python 3?
Thank you in advance.

Hi, I can run mnist example on a hadoop cluster(without GPU) properly. However, when I run the Cifar10 example, I got an error. Are the sh codes proper? Does this example support CPU mode? Should I modify the batch size?

Driver stacktrace:
I am using Spark 2.0.2 in StandAlone mode, TensorFlow 1.2 and pip provided TensorFlowOnSpark, but the same problem happens with Spark 1.6.0. Although I followed the instructions from the standalone wiki page (i.e. I generated the training data for the specific cluster size) I would always encounter:
org.apache.spark.SparkException: Can only zip RDDs with same number of elements in each partition
The problem is that the zip
operation assumes that the number of partitions AND the number of elements within each partition will be the same. Spark guarantees the number of partitions but not that all partitions have exactly the same number of elements. Thus, the operation of zipping the images with the labels fails.
Hello,
Using ami-f6d25596 nvidia library is 367 version and "nvidia-smi" works properly. After a while nvidia library becomes nvidia-375 and i received the message "Failed to initialize NVML: Driver/library version mismatch".
There is some process updating library i couldn't find.
After restoring 367 version and rebooting instance it works again.
I got the following error when executing the following
zip -r tfspark.zip tensorflowonspark

I'm running the MNIST example on a standalone cluster in Windows. I had to make a few changes to enable Python 3 support (I'm using 3.5):
In TFCluster.py (due to changes in relative imports):
from . import TFSparkNode
In TFSparkNode.py (Queue > queue and relative imports again, also a problem with Python 3 not handling UUID objects the same as 2):
from . import TFManager
...
authkey = uuid.uuid4()
authkey = authkey.bytes
... and then I get stuck with a pickling issue:
Caused by: org.apache.spark.api.python.PythonException: Traceback (most recent call last):

Not really how to proceed from here. I tried to use another library (dill) to do the pickling but that isn't working. Has anybody gotten this to work in Python 3?

I have a Spark cluster, each of them has 64 cores and 256 G RAM, I tried run MNIST training with TFoS and TF only, the results was out of my expectation.
The training on TFoS took took 25m53s with 100 epochs, here is the script:
spark-submit
--master yarn
--deploy-mode cluster
--num-executors 3
--executor-memory 32G
--py-files TensorFlowOnSpark/tfspark.zip,TensorFlowOnSpark/examples/mnist/spark/mnist_dist.py
--conf spark.dynamicAllocation.enabled=false
--conf spark.yarn.maxAppAttempts=1
--archives hdfs:///user/spark/Python.zip#Python
TensorFlowOnSpark/examples/mnist/spark/mnist_spark.py
--images mnist/csv/train/images
--labels mnist/csv/train/labels
--mode train
--model mnist_model
--epochs 10
However it only took 834s for training with TF only with 1000 epochs.
I didn't have chance to investigate to TFoS, is the performance related to training data size and some other elements?
