@sbrunk thanks, didnt know such things are possible. I will have to figure out sth that works in Jupyter lab, but now I have all the pieces on almond side.
Henry
@hygt
@sbrunk yes I've gotten to a point where it works. I've built the Almond launcher with coursier's --assembly-rule exclude-pattern ... to get rid of Jackson and Json4s classes. No more binary compatibility issues
my setup is tricky because our codebase shares way too much code between our services and Spark jobs
we can get around bin compat issues with sbt-assembly shading rules
but I was a bit tired of moving 100+ MB fat JARs around just to do some exploration with the Spark shell

@hygt
also our data scientists would rather use notebooks :smiley:

@larroy
is almond working? I'm trying to run it in jupyter notebook and finding all kinds of problems
First i bumped in this issue: almond-sh/almond#508
now seems the kernel it's hanging
is there a way to debug it?
I separated my statements into smaller chunks and now seems to work
weird

@Krever
how would you approach rendering basic grapgh diagram? just some nodes and edges

@Krever
@alexarchambault I see that in master ammonite is in ver 2.0.4 but cs resolve -t sh.almond:scala-kernel_2.13.1:0.9.1 shows it in 1.7.4. Could we have a release with the newer version?
Sören Brunk
@sbrunk
@Krever Alex has just released 0.10.0 which updates ammonite to 2.1.4

Hello People
I am running almond with docker with: docker run -it --rm -p 8888:8888 almondsh/almond:latest. How can I access my local file system?
I want to read a file in /sysroot/home/victor/Documentos/test.csv
Sören Brunk
@sbrunk
@vherasme you can use the -v option to mount a host directory into your container. See https://docs.docker.com/storage/bind-mounts/#start-a-container-with-a-bind-mount
Sören Brunk
@sbrunk
docker run -it --rm -v /sysroot/home/victor/Documentos/:/home/jovyan/data -p 8888:8888 almondsh/almond:latestshould work for you

@vherasme
Thanks a lot. One last thing, it won't allow me to create new notebooks: An error occurred while creating a new notebook. Permission denied: data/Untitled.ipynb
I was able to create the notebook in the work directory. Will this notebook disappear once I quit?
Sören Brunk
@sbrunk
Yes only the data directory will persist. You should check the write permissions of your documents dir. Or you could also mount another directory too.

Hi All, is there currently a way to install the almond.sh kernel in offline mode? I am unfortunately behind the corporate firewall and cannot install it with suggested in the docs ./coursier launch almond -- --install . I saw the issue on GitHub: almond-sh/almond#145 however the link in the answer is not valid anymore. I'd appreciate tips on how to go about it. Thanks!
Sören Brunk
@sbrunk
@mrjoseph84 You could try to generate a standalone launcher as described in the docs: https://almond.sh/docs/install-other#all-included-launcher

Hello, is there any way to pass the Spark conf parameters via environment variables so. that you don't need to specify them in the notebook? For PySpark it's PYSPARK_SUBMIT_ARGS pyspark-shell, for Zeppelin it's SPARK_SUBMIT_OPTIONS in conf/zeppelin-env.sh (https://zeppelin.apache.org/docs/0.5.5-incubating/interpreter/spark.html). Is there any way to pass the envs in similiar way in Almond kernel (e.g. via some Ammonite configs)?
Alexandre Archambault
@alexarchambault
@mrjoseph84 SPARK_CONF_DEFAULTS is taken into account. It should contain a path. The file at that path is read, and should contain lines like spark.foo value (space separating property name from value). Lines starting with # are ignored.
That doesn't allow to specify the options directly in an environment variable though. But support for it could be added. It should be a matter of adding some logic reading an env var around here.

@alexarchambault thanks! This is exactly what we used.

Hi All, I need help, I had some problems on the run of spark in yarn mode on Jupiter using almond, I got always the error: Caused by: java.io.IOException: No FileSystem for scheme: http
Instead, If I use ammonite shell and import the same library it works
this is my snippet of code:
import $ivy.`org.apache.spark::spark-sql:2.4.0`
import $ivy.`sh.almond::ammonite-spark:0.5.0` 
import org.apache.spark.sql._

val spark = {
  AmmoniteSparkSession.builder()
    .master("yarn")    
    .config("spark.executor.instances", "20")
    .config("spark.executor.memory", "2g")
    .getOrCreate()
}
def sc = spark.sparkContext

val rdd = sc.parallelize(1 to 100000000, 100)

val n = rdd.map(_ + 1).sum()
I use almond:0.5.0 --scala 2.11.12
ammonite:1.6.7

I'm getting Error: Unable to access jarfile /opt/conda/share/jupyter/kernels/scala/launcher.jar after installing; I know I can probably just chmod +r /opt/conda/share/jupyter/kernels/scala/ but did I do something wrong for it to be installed with -rwx------?

Is it possible to get widgets along the lines of ipython widget's file upload or select? I haven't seen any examples doing more than string inputs.

Hi all, I'd like to store snippets of code from a cell in Jupyter directly to a text file. In IPython, one could do that using magic commands (%...). Any pendant to that in Almond? I found some discussions from 2016 stating it's not possible, but maybe things changed in the meantime? Thanks

Hi, I'm trying to use the almond kernel with jupyter-book, but it doesn't like the ANSI color codes generated by ammonite. It is supposed to be possible to turn off the colors with interp.colors() = ammonite.util.Colors.BlackWhite, but that doesn't seem to have any effect from within Jupyter (no errors, it just doesn't turn off the color). It does work from an ammonite REPL. Any ideas? I don't want to file an issue before I know whether this is on the almond side or the ammonite side (and there's already an issue with jupyter-book to handle colors, but I don't think it's going to happen soon).

Hi there, I'm importing a script in a notebook through import $file.script. It looks like that once the script is compiled successfully and imported will no longer be reimported also if the script changes when the cell is newly evaluated. Is there a way to force the compilation or the reimport of the script without restarting the kernel?

Hi, it looks like almond is not downloading runtime dependencies of libraries: If I run

import $ivy.`io.grpc:grpc-core:1.30.2`
io.perfmark.PerfMark

I get "object perfmark is not a member of package io", while perfmark should be a runtime dependency for grpc-core, and should be downloaded and put on the classpath as well. Is there some setting to change this behavior?

apologies if this is too deep of a jupyter vs. jupyterlab question.

I have a custom kernel written on top of Almond and it works great in old jupyter notebook.

The main crux is that in execute I start a computation asynchronously and immediately return success:

          val id: String = ...

          ExecuteResult.Success(
            DisplayData.markdown("_awaiting results_").withId(s"$id-output"))

And then the async process will use $id-output to render the results as html.

all the other output updates work in jupyterlab apart from rendering the final output. Has anything changed in Almond's/Jupyter's API?

Hi, when trying to add a repository in Almond I keep getting:

cmd1.sc:3: object repositories is not a member of package ammonite.interp
val res1_1 = interp.repositories() ++= Seq(/*...*/)

Current code reads:

import coursierapi._

interp.repositories() ++= Seq(/*...*/)

How do I fix this?

Does the Almond Kernel support embedding into another Application? I.e. some application that starts it as a thread so the kernel has access to to all the classes of the JVM context (via the same class loader so the static variables are shared)
20 replies
I added support for this in the Kotlin Jupyter Kernel recently (Kotlin/kotlin-jupyter#102) and have a real use case for this
Florian Magin
@fmagin
it seems like it should support embedding like I described, if the class loader option (-i as far as I understand) is set to false. Will give this a try some time

I am trying to use Spark 3.0 with the local standalone cluster setup. I just simply create 1 master and 1 worker locally. However, the job is keep crashing with the issue

20/11/23 15:55:24 ERROR CoarseGrainedExecutorBackend: Executor self-exiting due to : Unable to create executor due to null
...
Caused by: java.io.IOException: No FileSystem for scheme: http
    at org.apache.hadoop.fs.FileSystem.getFileSystemClass(FileSystem.java:2660)
    at org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:2667)

It seemed all jars are uploaded to the Spark remote server and Spark trying to fetch them.

import $ivy.`org.apache.spark:spark-sql_2.12:3.0.0`
import org.apache.spark.sql._

val spark = {
  NotebookSparkSession.builder()
    .master("spark://localhost:7077")
    .getOrCreate()
}
spark.conf.getAll.foreach(pair => println(pair._1 + ":" + pair._2))
def sc = spark.sparkContext
val rdd = sc.parallelize(1 to 100000000, 100)
val n = rdd.map(_ + 1).sum()

You can reproduce by using the above code (and please create a standalone cluster beforehand

curl -O https://archive.apache.org/dist/spark/spark-3.0.0/spark-3.0.0-bin-hadoop2.7.tgz
tar zxvf spark-3.0.0-bin-hadoop2.7.tgz
