Hi,
sorry a completely unrelated question.
when is the upcoming release of SPARK 3.0. There are several parallel
distributed deep learning frameworks that are being developed, do you think
that we could use SPARK 3.0 for distributed deep learning using Pytorch or
Tensorflow?
Is there any place w
There was a change in the binary format of Arrow 0.15.1 and there is an
environment variable you can set to make pyarrow 0.15.1 compatible with
current Spark, which looks to be your problem. Please see the doc below for
instructions added in SPARK-2936. Note, this will not be required for the
upcom
Thanks for sharing that. I think we should maybe add some checks around
this so it’s easier to debug. I’m CCing Bryan who might have some thoughts.

SOLVED!
thanks for the help - I found the issue. it was the version of pyarrow
(0.15.1) which apparently isn't currently stable. Downgrading it solved the
issue for me

Hi,
Thanks for your reply.
Tried what you've suggested and still getting the same error.
Also worth mentioning that when I tried to simply write the dataframe to S3,
without applying the function, it works.

Can you switch the write for a count just so we can isolate if it’s the
write or the count?
Also what’s the output path your using?

Hi,
I'm using pandas_udf and not able to run it from cluster mode, even though the
same code works on standalone.
The code is as follows:
schema_test = StructType([
StructField("cluster", LongType()),
StructField("name", StringType())
])
@pandas_udf(schema_test, PandasUDFType.GROU
just try using an apply on a series for a custom function or on any other
library. Advertisement and actual delivery are two different skills
altogether. Not everyone wants to add a one to their column using the
pandas udf as one of their links shows :)
Most of the actual used cases are more aroun

this information is not widely spread. this is good to know. in which
circumstances is it worst than regular udf ?

And also be aware that pandas UDF does not always lead to better
performance and sometimes even massively slow performance.
With Grouped Map dont you run into the risk of random memory errors as well?

Hi,
BinaryType support was not added until Spark 2.4.0, see
https://issues.apache.org/jira/browse/SPARK-23555. Also, pyarrow 0.10.0 or
greater is require as you saw in the docs.
