umapr seed issue: cannot be used to seed a numpy.random.RandomState instance

[mhimanshu11]

Hi,

I am using the r wrapper function of UMAP, with all the requirements satisfied but unfortunately I cannot set the seed into the umapr function.
e.g. umapr::umap(iris[,1:4], n_neighbors = 5, random_state = 4), I always ran into the following error

Error in py_call_impl(callable, dots$args, dots$keywords) :
ValueError: 4.0 cannot be used to seed a numpy.random.RandomState instance

However, if I remove the random_state parameter, its working fine but not reproducible, could you please suggest what could be the reason behind it and any help in solving the error?

Thank you,
Himanshu

Hi, I will try to look into this more later, but my first guess is that Python is looking for an integer value but not getting that from R. Try random_state = 4L to force the 4 to be an integer. You might also check out two other packages, as described on the github README page: Recently, two new UMAP R packages have appeared. These new packages provide more features than umapr does and they are more actively developed. These packages are: - umap <https://github.com/tkonopka/umap>, which provides the same Python wrapping function as umapr and also an R implementation, removing the need for the Python version to be installed. It is available on CRAN <https://cran.r-project.org/web/packages/umap/index.html>. - uwot <https://github.com/jlmelville/uwot>, which also provides an R implementation, removing the need for the Python version to be installed.
