I'm suspecting that the issue is that you are passing a whole DataFrame rather than a single str. So it iterates over the entries of the DataFrame rather than the characters of the str. Try the following:

Which version of Sbt and Sbt assembly to use for Spack 2.4.5 and Scala 2.11?

Asked 2020-Sep-07 at 18:14

Currently, in AWS EMR Cluster, I am using Spark v2.4.5 which comes with Scala v2.11. So in my project, I want to use Scala v2.11 and corresponding SBT and Sbt-Assembly versions. But I am getting one or the other Version conflicts with all the permutations available on various blogs and Stackoverflow answers.

Here is my dependency files which throws error:

build.sbt

ANSWER

Answered 2020-Sep-07 at 18:14

It seems that you're mixing up the Scala version used by SBT and Scala version used in your project.

If you need to build project with Scala 2.11, it's just enough to specify in build.sbt

OSError: [Errno 8] Exec format error when running subprocess.Popen

Asked 2018-Jul-22 at 21:48

Im trying to run some open source code I downloaded from github: https://github.com/augustoqm/MCLRE

The code is running from my mac shell. When it reaches the subprocess.Popen() function it raise an "OSError: [Errno 8] Exec format error".

The code:

Start the new process

mrbpr_cmd_args = '%s -m %s -d %s -u %s -n %s -o %s -k %d -s %d -h %d -l %f -f %d -i %d -a %s -e "%s" -r "%s" -M %s' \ % (mrbpr_bin_path, meta_file, train_files, test_users_file, test_candidates_file, output_dir, rank_size, \ save_model, algorithm, learn_rate, num_fact, num_iter, relation_weights, regularization_per_entity, \ regularization_per_entity, model_name)

proc = subprocess.Popen(shlex.split(mrbpr_cmd_args), shell=True)

When I print "mrbpr_cmd_args" variable the results are:

/Users/nastia/Desktop/MCLRE-master/src/recommender_execution/mrbpr/mrbpr.bin -m /Users/nastia/Desktop/MCLRE-master/data/experiments/recsys-15/bpr-net_meetup.meta -d /Users/nastia/Desktop/MCLRE-master/data/partitioned_data/san_jose/partition_12/mrbpr/user-event-rsvp_train.tsv,/Users/nastia/Desktop/MCLRE-master/data/partitioned_data/san_jose/partition_12/mrbpr/user-user-same-group_train.tsv,/Users/nastia/Desktop/MCLRE-master/data/partitioned_data/san_jose/partition_12/mrbpr/user-user-same-event_train.tsv -u /Users/nastia/Desktop/MCLRE-master/data/partitioned_data/san_jose/partition_12/mrbpr/users_test.tsv -n /Users/nastia/Desktop/MCLRE-master/data/partitioned_data/san_jose/partition_12/mrbpr/event-candidates_test.tsv -o /Users/nastia/Desktop/MCLRE-master/data/experiments/recsys-15/san_jose/recommendations/partition_12/mrbpr -k 100 -s 0 -h 0 -l 0.100000 -f 200 -i 600 -a 0.25,0.15,0.6 -e "" -r "" -M BPR-NET_200-0.1-600-0.25:0.15:0.6

Can anyone please tell me what is wrong with this args?

From the README on the GitHub repo you linked:

Requirements

Linux: all experiments were executed in Linux-based machines, Ubuntu distributions, more specifically

And, if you look at that path inside the repo, mrbpr.bin is a Linux executable binary. You can't run that on a Mac.

If they provide the source to build that executable yourself, or a link to where to find it, you could probably build a Mac version. But, failing that, there's nothing you can do to fix it.

The best option would probably be to run a Linux container, virtual machine, or user-mode installation (either on your Mac, or on some free cloud host), install Python and all of the other requirements into that, and run the code that way.

If you're wondering why you got that particular error:

One method:

Use pivot_table and if one value per user and movie id then aggfunc doesn't matter, however if there are multiple values, the choose your aggregation.

In the doc it says in some systems the mode parameter is ignored or not well interpreted:

On some systems, mode is ignored. Where it is used, the current umask value is first masked out. If bits other than the last 9 (i.e. the last 3 digits of the octal representation of the mode) are set, their meaning is platform-dependent. On some platforms, they are ignored and you should call chmod() explicitly to set them.

And it suggest you to use chmod() instead
