I downloaded a Python 3.5 application which needs to import requests, overpy, numpy and tk. So, when I try to import, say, requests, I get:
Traceback (most recent call last): File "", line 1, in
ImportError: No module named 'requests'
I have searched the internet for answers and the best I could find is in this link getting error for importing numpy at Python 3.5.1 . I do have other versions installed, 2.7 is installed by default, however knowing where the problem is doesn't offer a solution.
If it is relevant to configuration issues, I have a Mac with El Capitan.
Do you have pip installed? It's likely that you don't have the package readily available. You will need to download pip for your operating system (if you haven't already), then run
pip install requests
http://docs.python-requests.org/en/master/user/install/
If you have pip installed and think you have requests installed as well, then run
pip freeze
It's most likely not an issue with your python versions, though you will want to be sure when you install pip that it is installed in the correct location.

I'm trying to install tensorflow from source on a Gentoo system (I think I need to do this to get it to use CUDA 9.1).
I'm able to build tensorflow, and then install it as a user with:
pip3 install --no-cache-dir --user /tmp/tensorflow_pkg/tensorflow-1.6.0rc1-cp35-cp35m-linux_x86_64.whl
When I try to import tensorflow I get:
>RuntimeError Traceback (most recent call last)
>RuntimeError: module compiled against API version 0xc but this version of numpy is 0xb
>
>ImportError Traceback (most recent call last)
>ImportError: numpy.core.multiarray failed to import
>
>ImportError Traceback (most recent call last)
>ImportError: numpy.core.umath failed to import
>
>ImportError Traceback (most recent call last)
>ImportError: numpy.core.umath failed to import
So my guess is that tensorflow was built against a different version of numpy than my system default (1.13.3).
The question is how to fix it? There's a lot about this process that's unfamiliar to me, so I would be grateful for any pointers in doing any of the following:
Telling the tensorflow build to use the system-wide numpy. Tensorflow uses bazel for the build process
Figure out what version of numpy tensorflow wants and change my system numpy to that.
Something else??? I can't do much with pip on a system-wide level because pip and Gentoo don't get along. I tried installing via Anaconda but then tensorflow couldn't see my gpus. Installing in a virtualenv with pip (which used to work) didn't work, I think because I've got cuda 9.1 installed. Perhaps I should downgrade to 9.0???
Any help appreciated!
Someone I always figure out how to do something the second after I post on SO! I installed into a virtualenv and did pip3 install --upgrade numpy in the virtualenv. All appears to be well...
I'm seeing the following error when installing TensorFlow:
ImportError: Traceback (most recent call last):
File ".../graph_pb2.py", line 6, in
from google.protobuf import descriptor as _descriptor
ImportError: cannot import name 'descriptor'
This error signals a mismatch between protobuf and TensorFlow versions.
Take the following steps to fix this error:
Uninstall TensorFlow.
Uninstall protobuf (if protobuf is installed).
Reinstall TensorFlow, which will also install the correct protobuf dependency.
I faced the similar issue, after trial and error, I used the below logic to run the program:
pip install --upgrade --no-deps --force-reinstall tensorflow
This will make sure to uninstall and reinstall the program from fresh. It works!
I would be extra careful before uninstalling/reinstalling other packages such as protobuf. What I think would most likely be the issue is difference in versions. As of writing this, the most recent release of python is 3.7 while tensorflow is only compatible up to 3.6.
If you're using a 3rd party distribution like Anaconda, this can get hidden from you. In this case I would recommend creating a new environment in Anaconda, with python 3.6 and then installing tensorflow: https://conda.io/projects/conda/en/latest/user-guide/getting-started.html#managing-python
Try this:
pip uninstall protobuf
brew install protobuf
mkdir -p
/Users/alexeibendebury/Library/Python/2.7/lib/python/site-packages
echo 'import site;
site.addsitedir("/usr/local/lib/python2.7/site-packages")' >>
/Users/alexeibendebury/Library/Python/2.7/lib/python/site-packages/homebrew.pth
I'm trying to change table wrote by me on tkinter with the pandastable one in order to do the handling of data directly from a pandas.DataFrame.
But despite I have already installed Anaconda3 with matlplotlib, numpy, pandas ect. modules when i would like to import pandastable I have trouble.
This is the problem:
import pandastable
Traceback (most recent call last):
File "<pyshell#8>", line 1, in <module>
import pandastable
ImportError: No module named 'pandastable'
pip install pandastable
Requires python>=3.3 or 2.7 and numpy, matplotlib and pandas.
See: pandastable on github
edit: You may have multiple Python environments installed on your machine. Anaconda uses conda install to keep things in check but pandastable doesn't seem to be available through Anaconda packages. Make sure you are installing to the same Python environment that your script uses. You might also try:
pip3 install pandastable
I'm interested in trying out sympy with Blender (v2.76, Python 3.4.2 Console, Windows 8.1). I followed this answer from Blender SE, downloaded sympy as a ZIP from Githib, and moved the sympy folder to C:\Program Files\Blender Foundation\Blender\2.76\python\lib\site-packages. However, when I opened Blender and tried to import sympy in the Python Console, I got the following error:
>>> import sympy
Traceback (most recent call last):
File "<blender_console>", line 1, in <module>
File "C:\Program Files\Blender Foundation\Blender\2.76\python\lib\site-packages\sympy\__init__.py", line 20, in <module>
raise ImportError("SymPy now depends on mpmath as an external library. "
ImportError: SymPy now depends on mpmath as an external library. See http://docs.sympy.org/latest/install.html#mpmath for more information.
I don't know how to install an external library. I tried going to the link mentioned in the ImportError, and I saw pip install mpmath. I tried it in cmd, but got this:
>pip install mpmath
Requirement already satisfied (use --upgrade to upgrade): mpmath in c:\anaconda3
\lib\site-packages
I did install Anaconda a while ago, so I guess it makes sense to have this output. How can I install mpmath as an external library for Blender so I can import sympy in it?
You want to install mpmath into blenders python folder, the same as you have done for sympy.
Your example of running pip was done in a system installed python that is setup to find the mpmath that you have installed in c:\anaconda3\lib\site-packages
Another option is to use the existing install of mpmath and sympy by adding your existing path to sys.path or adding it to the PYTHONPATH environment variable before you start blender.
I am having a hard time installing lxml(3.1.0) on python-3.3.0. It installs without errors and I can see the lxml-3.1.0-py3.3-linux-i686.egg in the correct folder (/usr/local/lib/python3.3/site-packages/), but when I try to import etree, I get this:
from lxml import etree
Traceback (most recent call last):
File "", line 1, in
ImportError: /usr/local/lib/python3.3/site-packages/lxml-3.1.0-py3.3-linux-i686.egg/lxml/etree.cpython-33m.so: undefined symbol: xmlBufContent
I did try to install with apt-get, I tried "python3 setup.py install" and I did via easy_install. I have to mention that I have 3 versions installed (2.7, 3.2.3 and 3.3.0.), but I am too much of a beginner to tell if this has to do with it.
I did search all over, but I could not find any solution to this.
Any help is greatly appreciated!
best,
Uhru
You should probably mention the specific operating system you're trying to install on, but I'll assume it's some form of Linux, perhaps Ubuntu or Debian since you mention apt-get.
The error message you mention is typical on lxml when the libxml2 and/or libxslt libraries are not installed for it to link with. For whatever reason, the install procedure does not detect when these are not present and can give the sense the install has succeeded even though those dependencies are not satisfied.
If you issue apt-get install libxml2 libxml2-dev libxslt libxslt-dev that should eliminate this error.
