Did you had any problems running?

Can't install. VC link error.

Is it pywFM specific or something else? Can you be post the error?

freepose commented

Thanks for the reply. the path error. C:\libfmlibFM -> C:\libfm\libFM

C:\libfmlibFM -task r -train C:\Users\freepose\AppData\Local\Temp\tmpzwbvgpz5 -test C:\Users\freepose\AppData\Local\Temp\tmpvi5z303h -dim '1,1,8' -init_stdev 0.1 -iter 5 -method mcmc -out C:\Users\freepose\AppData\Local\Temp\tmpkf6xo9si -verbosity 0 -save_model C:\Users\freepose\AppData\Local\Temp\tmp_ut9e2b0 -rlog C:\Users\freepose\AppData\Local\Temp\tmpxs95f65x

This shouldn't be the case since we recently had a PR that fixed this. But you can fix this by editing your LIBFM_PATH var, and adding a '/' at the end.

freepose commented

Thanks for your suggestions.

  1. LIBFM_PATH var has been added a suffix: ''.
  2. The pywFM has been run up.
  3. Another problem is: could the sparse vector (input format of libsvm) be used as the input format of pywFM?

best regards

jfloff commented

Regarding 3. pywFM is a python wrapper for libFM. libFM uses the sparse vector, so if you intend to use that input format, I recommend you to use libFM directly.

Closing the issue. Thank you for you feedback!

Thanks many much!

Hello,
I am trying to run the pywFM code example on Windows 10 in a Jupyter Notebook environment, but I'm encountering an error. Can someone help me find a solution for this error?

import pywFM
import numpy as np
import pandas as pd
import os

os.environ['LIBFM_PATH'] = r"C:\Users\test\AppData\Local\Programs\Python\Python311\Lib\site-packages\pywFM\libfm"

features = np.matrix([
# Users | Movies | Movie Ratings | Time | Last Movies Rated
# A B C | TI NH SW ST | TI NH SW ST | | TI NH SW ST
[1, 0, 0, 1, 0, 0, 0, 0.3, 0.3, 0.3, 0, 13, 0, 0, 0, 0 ],
[1, 0, 0, 0, 1, 0, 0, 0.3, 0.3, 0.3, 0, 14, 1, 0, 0, 0 ],
[1, 0, 0, 0, 0, 1, 0, 0.3, 0.3, 0.3, 0, 16, 0, 1, 0, 0 ],
[0, 1, 0, 0, 0, 1, 0, 0, 0, 0.5, 0.5, 5, 0, 0, 0, 0 ],
[0, 1, 0, 0, 0, 0, 1, 0, 0, 0.5, 0.5, 8, 0, 0, 1, 0 ],
[0, 0, 1, 1, 0, 0, 0, 0.5, 0, 0.5, 0, 9, 0, 0, 0, 0 ],
[0, 0, 1, 0, 0, 1, 0, 0.5, 0, 0.5, 0, 12, 1, 0, 0, 0 ]
])

target = [5, 3, 1, 4, 5, 1, 5]
features = np.asarray(features)
fm = pywFM.FM(task='regression', num_iter=5)

model = fm.run(features[:5], target[:5], features[5:], target[5:])

The error message I'm encountering is:
File ~\AppData\Local\Programs\Python\Python311\Lib\site-packages\pandas_libs\parsers.pyx:555, in pandas._libs.parsers.TextReader.cinit()
EmptyDataError: No columns to parse from file

I would appreciate any assistance in resolving this issue.
