ImportError: cannot import name sigtools
Apparently the sigtools import fails, but I can't figure out why. The /usr/lib/python2.7/site-packages/scipy/signal contains all files:
$ ls -1 /usr/lib/python2.7/site-packages/scipy/signal/sign*
/usr/lib/python2.7/site-packages/scipy/signal/signaltools.py
/usr/lib/python2.7/site-packages/scipy/signal/signaltools.pyc
In general, how python process directives like this, specifically what dot is resolved to if my working directory was completely different from the location where sigtools package is located?
from . import sigtools
As stated here:
`from ... import` vs `import .`
"from . import sigtools" imports the main module "." (which is "signal") than imports the object/module sigtools. If "." has been already imported it rely on that structure.
I think that this can be tricky in case you have 2 modules with the same name in the python import path: the interpreter imports the first one found and never imports the second one. If the second one has more modules than the first one, this can lead to something similar to your problem.

The first cell of my jupyter notebook contains the libraries I want to import. For some reason when I run it receive the ImportError: cannot import name randbits. I have never seen this import error before and have already tried restarting the kernel and confirmed that all libraries were installed correctly. As anyone seen this before and know what to do about this error?

I have been having the same issue all day. Finally figured out what solved my problem. Somehow anaconda3/Lib/secrets.py got overwritten. Numpy relies on files in this directory called random.py and secrets.py so if you have files with those names numpy will not load.
-I renamed my incorrect secrets.py file
-Found the secrets.py source code and recreated the file. Solved my issue. Hope it helps. The links below were the most beneficial for me.

I am trying import a module in Jupyter and it is not working:
import alyn
ImportError Traceback (most recent call last)
<ipython-input-8-8e9535ea4303> in <module>()
----> 1 import alyn
~\Anaconda3\envs\tracx\lib\site-packages\alyn\__init__.py in <module>()
1 """ Import required modules"""
----> 2 from deskew import *
3 from skew_detect import *
ImportError: No module named 'deskew'
I don't quite understand why, since the package in question has a correct init.py file:
whose contents are:
""" Import required modules"""
from deskew import *
from skew_detect import *
What am I missing?
P.S.
This is all taking place on Windows 10.
Well, I've figured it out!
Turns out that the package I was trying to import is written in Python 2 and its init file is using the relative import mechanism. However, I am working in Python 3 and relative import is no longer supported in it. The init file can be made to work in Python 3 by adding a . in both lines, like this:
""" Import required modules"""
from .deskew import *
from .skew_detect import *
I think this should be backward compatible with Python 2.
I'm trying to port over a python project from v2.x, to v3.x
one of the major changes to python was the import system.
I am now seeing an error when trying to load my python notebook as follows
package/
__init__.py
bh_tsne.py
Collect Samples.ipynb //imports utils.list_all_files, sees error
Error Output

strangely.. I think the problem is a circular dependence.. but bh_tsne doesn't rely on any utilities.. could the circularity be coming from my utils.list_all_files and then the __init__.py ?
bh_tsne imports
from argparse import ArgumentParser, FileType
from os.path import abspath, dirname, isfile, join as path_join
from shutil import rmtree
from struct import calcsize, pack, unpack
from subprocess import Popen
from sys import stderr, stdin, stdout
from tempfile import mkdtemp
from platform import system
from os import devnull
import numpy as np
import os, sys
import io
Edit
Is that redundant os.path join perhaps the root cause?
I ended up just upgrading the wrapper that was used in one project from it's source upstream project. The original owner had done upgrades.
https://github.com/lvdmaaten/bhtsne/blob/master/bhtsne.py
and the import worked after that as
import utils.bhtsne as bhtsne
I found out that bh_tsne seems NOT to work with python 3. Also another version (Multicore TSNE) just work with python 2.7 as well
In Ubuntu 14.04, I have installed Graphlab based on https://dato.com/download/install-graphlab-create-command-line.html and it seems to be working fine.
However, I receive this error when trying to use a recommender module:
import graphlab
from graphlab.recommender import ranking_factorization_recommender
In the first line, graphlab is imported without any error. However, the second line causes this error:
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-5-34df81ffb957> in <module>()
----> 1 from graphlab.recommender import ranking_factorization_recommender
ImportError: No module named recommender
How can the problem be solved? Thanks
It's just a namespace issue. recommender actually lives in the `toolkits module, so this should work:
import graphlab
from graphlab.toolkits.recommender import ranking_factorization_recommender
Graphlab has already imported everything for you in their __init__.py file.
Just do:
from graphlab import ranking_factorization_recommender
from graphlab import <any_other_recommender>
Here is a snippet of graphlab.__init__.py file:
from graphlab.util import get_runtime_config

I've hit this weird issue were I'm unable to import from the math module in Python. However importing the entire module works.

I have no idea why this could be. Any help would be appreciated.

If you want to import the built-in math inside core.math, turn on absolute imports so you don't get core.math instead:
from __future__ import absolute_import
