Error: 'skipgram_cbow' is not an exported object from 'namespace:fastTextR'

[AnyaMit]

Hi -
I'm following this tutorial ( https://cran.r-project.org/web/packages/textTinyR/vignettes/word_vectors_doc2vec.html
)

ERROR:

Error in skipgram_cbow(input_path = PATH_INPUT, output_path = PATH_OUT,  : 
  could not find function "skipgram_cbow"

Running into an error when running the following code:

`vecs` = fastTextR::skipgram_cbow(input_path = PATH_INPUT, output_path = PATH_OUT, 
                                 method = "skipgram", lr = 0.075, lrUpdateRate = 100, 
                                 dim = 300, ws = 5, epoch = 5, minCount = 1, neg = 5, 
                                 wordNgrams = 2, loss = "ns", bucket = 2e+06,
                                minn = 0, maxn = 0, thread = 6, t = 1e-04, verbose = `2)`

Thank you for your help!

hello @AnyaMit,

have you installed the fastTextR package as described in the README.md file using

devtools::install_github('mlampros/fastTextR')

? I updated the README.md so that a user can install the package directly by downloading the .zip file.

Hi @mlampros,

Thank you for the fast reply. Yes, I have tried to download with devtools and zip file. During the install, the following message appears:

Hi @mlampros,

Was able to solve the issue. I downloaded the zip file from the repository page. Extracted it locally to my R library directory. Renamed the folder fastTextR. Then, ran 4 suggested lines from 'READ ME':

setwd('/your_folder/fastTextR/')
Rcpp::compileAttributes(verbose = TRUE)
setwd('/your_folder/')
system("R CMD build fastTextR")

but, instead of running the last line "(system("R CMD INSTALL fastTextR_1.0.0.tar.gz")", I installed the .zip file through R Studio GUI.

Not sure why that solved the issue, but the skipgram_cbow function works now.

@AnyaMit I guess the issue that you faced with system("R CMD INSTALL ...") is windows related (fastTextR can be installed on windows). However, it's good that you found a workaround to make it work.

[mlampros]

I close the issue for know. Feel free to reopen it in case that the function does not work as expected.

[AnyaMit]

Thank you.

I was also running into the same problem and tried the solutions suggested. Ugrading to rtools from 3.4 to 3.5 got the code working.

[AnyaMit]

Good to know there are multiple solutions. The tool is very useful. Thanks for putting it together.

hi @AnyaMit, @msmith01,

I uploaded the updated version of the fastText package. It can be installed only from Github as it wasn't finally accepted from CRAN due to the fact that there are already two other versions of the same algorithm.
There is also a blog post explaining the new functionality.
This repository will be archived. New issues can be opened only in the new repository. Thanks.
