Yeah that doesn't sound like a bad solution for now. I don't have access to a Windows-machine, so would you mind taking a crack at it @jlorince?

@jlorince It would be helpful if you can elaborate on the stopgap solution. I'm trying to run this in windows and os.fork
is causing the issues. Thanks in advance.
from bhtsne.
I ended up modifying the code to remove the fork. Turns out, fork is just used to make the command prompt responsive to keyboard interrupts. Removing that also makes this compatible with jupyter and spyder.
Just replace the function with this one:
def run_bh_tsne(data, no_dims=2, perplexity=50, theta=0.5, randseed=-1, verbose=False, initial_dims=50, use_pca=True, max_iter=1000):
'''
Run TSNE based on the Barnes-HT algorithm
Parameters:
----------
data: file or numpy.array
The data used to run TSNE, one sample per row
no_dims: int
perplexity: int
randseed: int
theta: float
initial_dims: int
verbose: boolean
use_pca: boolean
max_iter: int
'''
tmp_dir_path = mkdtemp()
if _is_filelike_object(data):
data = load_data(data)
init_bh_tsne(data, tmp_dir_path, no_dims=no_dims, perplexity=perplexity, theta=theta, randseed=randseed,verbose=verbose, initial_dims=initial_dims, use_pca=use_pca, max_iter=max_iter)
res = []
for result in bh_tsne(tmp_dir_path, verbose):
sample_res = []
for r in result:
sample_res.append(r)
res.append(sample_res)
rmtree(tmp_dir_path)
return np.asarray(res, dtype='float64')
