Error when trying to convert RandomForestClassifier to javascript

Hello @aflugge ,

can you set the compression level to 0? In Python 3.x the default value is 3 I guess.

from sklearn.externals import joblib
# ...
joblib.dump(clf, 'estimator.pkl', compress=0)

Thanks for the reply. Setting compress=0 does not seem to make any difference. However, with "from sklearn.externals import joblib" rather than "import joblib" as I have done before, I get the different error message as below:

Traceback (most recent call last):
File "/home/user/anaconda3/lib/python3.6/runpy.py", line 193, in _run_module_as_main
"main", mod_spec)

with open(dest_path, 'w') as file:
PermissionError: [Errno 13] Permission denied: '/RandomForestClassifier.js'

I did however manage to export my RandomForestClassifier from within Python with
porter = Porter(clf, language='js')
output = porter.export(embed_data=True)
print(output)
So that way it seems to work :)

Okay, I'm glad that it's working now 😄,

nevertheless, apparently the module hasn't the permission to create a file. Alternatively you can use python -m sklearn_porter -i estimator.pkl --js --pipe > estimator.js to save the output to a file dynamically.
