I am using Python for my Linear Algebra course for programming. For the tools we need, I am trying to install NumPy. I used this website to guide me through the installation process.
I started from the links on SciPy's OS X page and eventually arrived at the SourceForge download site.
From there, I chose the Mac OS X installer numpy-1.6.1-py2.7-python.org-macosx10.3.dmg.
When I went to Idle and typed in
>>> import numpy as np
This is the error I received:
Traceback (most recent call last):

/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/numpy/core/multiarray.so: no matching architecture in universal wrapper
I also tried it from the terminal and got the same error. I have a virtual environment installed - virtual env wrapper. I called the environment in the terminal by:
source my_new_env/bin/activate
And then I tried to import numpy in the terminal that way, but then I got the error:
(my_new_env) $ sudo python -c 'import numpy; numpy.test()'
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named numpy
I am not sure if I installed NumPy incorrectly or if my virtual environment is conflicting with Nose. If anyone has suggestions let me know!
i would skip the MacOS package install and use the 'pip install' instructions, since you're already familiar with virtualenvs. use these instructions instead: http://www.scipy.org/install.html#installing-via-pip
it's easier to work with a virtualenv and pip, which will ensure post-install that your virtualenv will have access to the modules you've installed. it takes more work to do that with an external package (or .dmg) that you've downloaded. not impossible, just more work. HTH.
Try these commands:
brew update, brew doctor
, because, in my case, I didn't even have to install numpy separately. Yet I could import numpy easily. Meanwhile you can try downloading the numpy package from this website.

I'm trying to use the tensorflow.io.gfile module to load an inference graph. When I try to import the gfile module, so I can get to the GFile class, I get the following results:
>>> import tensorflow
>>> from tensorflow.io import gfile
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'tensorflow.io'
No module named 'tensorflow.io'
>>> tensorflow.__version__
'2.0.0'
I'm on MacOS Catalina with Python 3.7.4.
How can I successfully import sub-modules of tensorflow.io if it's missing?
https://www.tensorflow.org/api_docs/python/tf/io/gfile/GFile
pip install tensorflow.io
Should solve the problem.
The answer relies on the assumption that you are using TF2.0, in which this functionality has been moved to a separate package.
I have installed PyQt3D in the same virtual environment where I have PyQt5 up and running properly. However, I cannot import PyQt3D
>>> import PyQt3D
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'PyQt3D'
The module is properly installed
$ pip list
PyQt3D (5.9.2)
PyQt5 (5.9.1)
How can I fix this ?
I found the answer by searching through my python packages using pydoc.
PyQt3D does not expose an importable module name, but rather it adds the following submodules to the PyQt5 package, which is consistent with Qt5 documentation:
Qt3DCore
Qt3DExtras
Qt3DInput
Qt3DLogic
Qt3DRender
Objects defined by these submodules can then be imported normally like this
from PyQt5.Qt3DCore import QEntity
When I follow the Installation for linux from tensorflow offical site, everything is fine until the last step: Train your first TensorFlow neural net model.
When I execute the command, python tensorflow/models/image/mnist/convolutional.py, An ImportError promps.
Traceback (most recent call last):
File "tensorflow/models/image/mnist/convolutional.py", line 13, in <module>
import tensorflow.python.platform
File "/home/guo/haplox/Github/tensorflow/tensorflow/__init__.py", line 4, in <module>

File "/home/guo/haplox/Github/tensorflow/tensorflow/python/__init__.py", line 13, in <module>
from tensorflow.core.framework.graph_pb2 import *
ImportError: No module named core.framework.graph_pb2
My OS is 14.04.1-Ubuntu.
I have met the exactly same issue. once your have installed the tensorflow successfully, it's not about the library dependency anymore.
if your executed the convolution.py 100% accurately as manual and get the exception like below
ImportError: No module named core.framework.graph_b2
this means you are executing the python script exactly under the cloned project root directory,let's say the root named "src".
src$python tensorflow/models/image/mnist/convolutional.py
please try to execute the script in the parent directory of the cloned root directory. for example, if your just clone the tensorflow under src dir, goto its parent dir like xxx and do it again.
xxx$python src/tensorflow/models/image/mnist/convolutional.py
bingo, it works like a charm!
I had the same issue and the solution was to uninstalled protocol buffer v2.6.
TensorFlow requires protocol buffer v3.0, which should come with your TensorFlow installation/source. Hope this helps.
Most probably you have either outdated version of:
python's six module. Install the newest one (pip install six) or upgrade your old one (pip install --upgrade six)
protobuf
I solved it by using virtualenv, but there are many other factors which may cause the same error.
More solutions are at Github issues #81, #61,
#51.
For me, the solution was to run with python3 instead python
Windows7 with python 3.4 32bit.
Downloaded and ran install according to this related question.
However I have a different error, so I posted a new question.
I removed the faulty install and tried the installer from the sourceforge link off matplotlib.org. Both finish claiming to be successful, though testing results in an error (both resulting in the same error)
from matplotlib import *
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
from matplotlib import *
File "C:\Python34\lib\site-packages\matplotlib\__init__.py", line 105, in <module>
import six
ImportError: No module named 'six'
Actually you need to install six. As given in Python Error: "ImportError: No module named six"
Better you can install pip and install all libraries using that.
I have a problem similar to this one below:
Python pip broken after OS X 10.8 upgrade
After installing ML, I can no longer use iPython, SciPy or Matplotlib. I get this error:
Shanes-MacBook-Pro:~ $ ipython
Traceback (most recent call last):
File "/usr/local/bin/ipython", line 5, in <module>
from pkg_resources import load_entry_point
File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2603, in <module>

File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 666, in require

File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 565, in resolve
raise DistributionNotFound(req) # XXX put more info here
pkg_resources.DistributionNotFound: ipython==0.14.dev
I have tried the following to fix it:
Using sudo ipython
Installing latest Xcode
Reinstalling SciPy superpack
When I type which python it says it is in /usr/bin/python.
Extra information:
nside /Library/python/2.7/site-packages
Inside there is the following:
DateUtils-0.5.2-py2.7.egg
README
easy-install.pth
nose-1.1.2-py2.7.egg
pika-0.9.5-py2.7.egg
pyzmq-2.2.0.1-py2.7-macosx-10.8-intel.egg
tornado-2.3-py2.7.egg
So with this ML upgrade, it removed my numpy, ipython, etc. And it does not install there anymore like it did with lion. How can I find where it installs too because it seems like it is working when I run the install_superpack shell script.
As an update, I never fixed this specific problem. However, I just downloaded the iPython, SciPy, Matplotlib etc. from Enthought. I answered someone elses question on how to do this here:
How to check whether I have IPython installed on my machine and what sequence to install these libraries?
