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.

So I wanted to import matplotlib to my virtual python version of 3.10.0 (and other versions). I install it as usual:
pip install matplotlib
Everything seems to work, no errors show up with pip. But when I try to run this code snippet in vs code (to see if mpl works):
import matplotlib
print(matplotlib.__version__)
It outputs this:
File "/Users/XYZ/Desktop//pienv.py", line 1, in <module>
import matplotlib
File "/Users/XYZ/Desktop//matplotlib.py", line 1, in <module>
import matplotlib.pyplot as plt
ModuleNotFoundError: No module named 'matplotlib.pyplot'; 'matplotlib' is not a package
But when I do the same in the terminal it outputs the correct version.
It doesn't matter if I have python installed with dmg file or with pyenv, result is the same.
I tried to format operating system to ensure there is no os trash that might be getting in a way. Then I just installed python with pyenv.
I'm using osx 12.0.1
My vscode setup is straightforward, just python extension and python interpreter set to what pyenv has as a local python.
Is there that can be done, or that I'm doing wrong?
Found the answer.
It's just a stupid thing.
Don't name your projects with the names of your libraries when they're in the same directory.
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 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.
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>
from tensorflow.python import *
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
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>

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?
