I am working on ubuntu 14.04. Python version: 2.7.6.
I am trying to install cPickle, but I am getting error:
"could not find any downloads that satisfy the requirement cPickle"
I tried via, pip and apt-get as well. What might be reason, has this package been removed completely?
Actually, I tried importing cPickle and it worked. But I don't know why the error "could not find any downloads that satisfy the requirement cPickle". I will appreciate if someone can provide reason.
Also as commented by mike cleared my doubt.
"cPickle is installed when python itself is installed -- it's part of the standard library. So, just import cPickle and it should be there"

I am fairly new to TensorFlow and just installed it with CPU-support-only version following to this: https://www.tensorflow.org/install/install_linux
My Ubuntu is 16.04 and python installed is 2.7.13. I chose "native" pip installation.
The download and install process went though smoothly, however, when I tried to import Tensorflow and use it, it returns following error;
ImportError: /usr/local/lib/python2.7/site-packages/tensorflow/python/_pywrap_tensorflow_internal.so: undefined symbol: PyUnicodeUCS4_FromString
I have got no clue how to solve it after crawling in google.
If you know some idea on how to solve this and could give me some advice, much appreciated.
Thank you so much in advance!
It's because your python is built with UCS2, which is incompatible with the one assumed by tensorflow (UCS4). So either you build your python with UCS4 (--enable-unicode=ucs4) or build tensorflow from source may solve this issue, I guess.
From the past two days, I've been trying to install scipy from the wheel file available from http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy in my windows laptop 64 bit built and running Python 2.7.3. I tried running pip install scipy in the command window, it didn't work and the following error popped up in command prompt
and
I also tried typing
pip install scipy-version.whl
That didn't work too! and the same error popped up. I even updated my pip.
I read in some comments that pip doesn't work well for scipy installation. If so, what alternatives can you suggest? If not can you tell me the way to install using wheel scripts?
There are some issue while installing scipy using pip, please try using Anaconda python version which comes with all the libraries you can ever need instead of your default python.
Still if you want to use the default python refer here, as already answered here.
I downloaded scipy-0.17.0-cp27-none-win_amd64.whl and GDAL-1.11.4-cp27-none-win_amd64.whl from gohlke in C:\Python27\Scripts
To install I used
pip install scipy-0.17.0-cp27-none-win_amd64.whl
pip install GDAL-1.11.4-cp27-none-win_amd64.whl
It says the installation is complete but when I import the libraries as
import scipy
import gdal
it shows error as
No module named gdal
No module named gdal
However, I installed the matplotlib, numpy in the very same way and they are working absolutely fine.
I solved this problem eventually to found the mistake in my approach.
This problem can occur with anyone using ArcGIS in one's system.
ArcGIS comes with it's default Python package and if one installs python separately, each time the new libraries gets installed in the newer Python installation not in ArcGIS.
Therefore, the pyhton IDLE which one uses need to be from another Python installation.
Here in my case, ArcGIS has Python 2.6 and I have made an separate installation using Python 2.7.11.
All the libraries were getting installed in right place but I was opening the wrong IDLE to write scripts hence getting error.
I found a code on internet which implement a paper "Effective 3D Action
Recognition Using EigenJoints" code. They implement in Python so I tried to install Python 2.7.9 and numpy, scipy, scikit-learn. All these libraries installed successfully. In the cmd when i tried to run python eigen.py it gives me this error.
Please anyone download this code and run it by yourself or help me to solve this error.
You have to do 2 steps:
download anaconda according to your system and specifications.
Make sure that Anaconda is installed on python version installed on your system. For example, if you have python 3.4, and anaconda in installled on 2.7, then you should remove python 3.4.
Afterwards, the code will run smoothly and all libraries will be well defined. I have made the same ;) Please, let me know if you face new problems.
I have used Scipy for some time. This is the first time I am using it for Signal processing!
But when I import modules like
from scipy import signal
from scipy import special
I get the error:
ImportError: DLL load failed: The specified module could not be found.
I am using Python 2.7.3 with Scipy 0.12.0 on 32-Bit Windows.
What should I do ?
This problem can be solved if instead of installing the usual numpy distribution, the numpy-MKL package is installed.
This package is available here.
Do remove the previous installation before going with the new one!
I already had numpy+mkl installed, but still I faced similar error.
Reinstalling has solved the issue:
pip uninstall numpy-1.13.1+mkl-cp35-cp35m-win_amd64.whl
pip install numpy-1.13.1+mkl-cp35-cp35m-win_amd64.whl
I installed numpy-MKL from here for Python 3.5.1, but it didn't solve the problem until I added the folder C:\Program Files\Python35\Lib\site-packages\numpy\core to system path.
Similar to the OP, I already had the Intel MKL libraries installed on my system. I was unable to load scipy.linalg with the same error message. I uninstalled the old version of numpy and scipy (which I installed before installing the Intel compilers and math libraries). Then ran pip install scipy, and magically I could now import scipy.linalg without the error.
I'm not entirely sure what caused it, and why it was unable to find the library it needed. But it somehow fixed the problem for me on Python 3.7.1 with Anaconda.
I had an issue importing sklearn because of my Scipy installation.
I fixed this by going to here and downloading the right version of numpy for my computer. Then I did the same for Scipy by going here and downloading the MKL version for my computer.
Once I did that, everything worked!
To check the supported tags for wheel version for your system you can run the following command in the command prompt: pip debug --verbose.
You can install the .whl files for numpy and scipy by doing: pip install {filename}.whl
I had this issue on 3.6 and reinstalling didn't work,downloading the wheel didn't work. I found a solution that did work:
go to "site-packages/scipy" folder and open __init__.py file for editting.
At the very bottom add this line of code:
from . import signal
from . import special
from . import linalg
from . import <insert missing submodule here>
this is the only solution that has worked for me and it should work for any one
