I believe I finally installed OpenCV using the following command.
conda install -c anaconda opencvÂ
it seems I can load opencv in python3
however, when I try to import this in ipython or jupyter, I get the following:
In [1]: import cv2
ImportError Traceback (most recent call last)
<ipython-input-1-72fbbcfe2587> in <module>()
----> 1 import cv2
ImportError: dlopen(/Users/mycomputer/anaconda/lib/python3.6/site-packages/cv2.cpython-36m-darwin.so, 2): Library not loaded: #rpath/libintl.8.dylib
Referenced from: /Users/mycomputer/anaconda/lib/libharfbuzz.0.dylib
Reason: image not found
By run this command:pip install opencv-python, I fixed this issue.

I had installed numpy on alpine docker and everything looked good before running numpy:
Traceback (most recent call last):

I found that licblas.so might be in /usr/lib/ as mentioned here: alpine blas
but it wasn't there.
After installing lapack, the missing file libcblas.so.3 appeared in /usr/lib/:
apk add lapack
I had openblas-dev installed from before but that was not sufficient.
Followed through installation tips, but after typing
$ python underactuated/src/double_pendulum/simulate.py
I get
ImportError: dynamic module does not define init function (init_module_py).
If I run python3 I get
ImportError: cannot import name 'FindResource'.
After typing $ python3 -c 'import pydrake; print(pydrake.__file__)' I get /opt/drake/lib/python3.6/site-packages/pydrake/__init__.py
Edit:
Full output of running python3
Traceback (most recent call last):
File "underactuated/src/double_pendulum/simulate.py", line 5, in <module>
from underactuated import FindResource, PlanarSceneGraphVisualizer
ImportError: cannot import name 'FindResource'
And full output of running python (without3):
Traceback (most recent call last):

from pydrake.all import (AddMultibodyPlantSceneGraph,

from ._module_py import *
ImportError: dynamic module does not define init function (init_module_py)
Version of python after typing python -V is Python 2.7.15+
The fact that the print test succeeds suggests that drake is installed correctly.
Please post the full output of running simulate.py with python3.
How manually install util on google colab?

anaconda - graphviz - can't import after installation
(14 answers)
Closed 3 years ago.
I cannot get graphviz to install and import properly, either using conda install or pip install. I am using jupyter on anaconda.
conda install -c anaconda graphviz
---------------------------------------------------------------------------
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-2-0e78fd6401bd> in <module>()
----> 1 import graphviz
2 dot_data = tree.export_graphviz(clf, out_file=None)
3 graph = graphviz.Source(dot_data)
4 graph.render("iris")
ModuleNotFoundError: No module named 'graphviz'
When I install using pip I can successfully import but when I run the below code, I get a very long error message that ends with the following when running graph.render:
from sklearn.datasets import load_iris
from sklearn import tree
import graphviz
iris = load_iris()
clf = tree.DecisionTreeClassifier()
clf = clf.fit(iris.data, iris.target)
dot_data = tree.export_graphviz(clf, out_file=None)
graph = graphviz.Source(dot_data)
graph.render("iris")
Below is the end of the end of a long error message:
ExecutableNotFound: failed to execute ['dot', '-Tpdf', '-O', 'iris'], make sure the Graphviz executables are on your systems' PATH
I have the directory where the graphviz folders are in PATH.
Anyone have an idea what I am doing wrong?
http://www.graphviz.org/Download_windows.php
Install windows package from: http://www.graphviz.org/Download_windows.php
Install python graphviz package
Add C:\Program Files (x86)\Graphviz2.38\bin to User path
Add C:\Program Files (x86)\Graphviz2.38\bin\dot.exe to System Path
RESTART COMPUTER
Worked for me!
If you're running Linux, you may have to run this command in addition to the Conda command (I had to do this):
sudo apt-get install graphviz
I was getting the exact same error in Pycharm and this solved it.

It looks like PIL is installed in the correct PATH and when I go to use it in Sublime I get the:

I'm hoping to figure out either how to change the PIL path to ammend it to my system python path so I can run it in my interpreter or to uninstal and redownload PIL the correct way.
I'm new to Mac OS and have been able to troubleshoot most everything until now. I'm guessing it's because I'm running off my sys Python 2.7 and not a brew installeld 2.7... can someone walk me through this?
