FileNotFoundError at subprocess about spmf-py

[LoLei]

I cannot reproduce this using your code on my system (Linux).

me@keyboard /tmp/spmf-test
$ ls -1
contextPrefixSpan.txt
spmf.jar
test.py

from spmf import Spmf
import pathlib

spmf_jar_dir = pathlib.Path(__file__).parent.absolute()

spmf = Spmf("PrefixSpan",
            input_filename="contextPrefixSpan.txt",
            spmf_bin_location_dir=spmf_jar_dir,
            output_filename="output.txt", arguments=[1, "", True])
spmf.run()

$ python3 test.py
>/tmp/spmf-test/spmf.jar

A few ideas:

• Can you try running the java command in your Windows command line?
  • (java -jar <your_path>spmf.jar run PrefixSpan contextPrefixSpan.txt output.txt 1 "" True)
  • This is the same command Python tries to execute in your code.
  • It might not be able to find your java executable, not the jar file.
• You mention "spfm.jar". I hope that's just a typo here and your file isn't actually called that.

Hi,
the problem was the java executable, thank you for replying.
