I run Windows 7, Enthought Python Distribution 7.3-2 Academic.
I open a command prompt, change to my code directory and type
U:\rsch>ipython notebook
In a new notebook, I type %pylab and receive the following error:

ImportError: DLL load failed: The specified path is invalid.
Not sure what to do. Thanks.
I experienced the same problem and here is what worked for me:
I made sure I call the IPython without "pylab"
I then made sure all sessions/instances (excuse me but I'm new to this :) are closed. You can do this by ctrl-C in all Terminals and in the Notebook dashboard press "shutdown" if possible.
There are probably more elegant ways to do this but this is what worked for me.
Developers, take note that many newbies might get very frustrated when the first notebook they try to run gives them an error.

It's likely that you're missing the Scripts directory in your system path. To check, run
echo %PATH%
from the command prompt and look for D:\Python27\Scripts. If it's missing, you can add it manually from the Control Panel, or using a utility like Rapid Environment Editor.
EPD shipped with ipython 0.12. Ipython has developed a lot since then. You should update to ipython 0.13.1 by entering "enpkg ipython", as described in more detail here:
https://support.enthought.com/entries/22415022-Using-enpkg-to-update-EPD-packages
Unfortunately these error messages arent really useful. From the message you only know that 'some dll' fails to import during the import of "lapack_lite" (part of Numpy).
You can use Dependency Walker to see which specific DLL is causing the problem, opening "D:\Python27\Lib\site-packages\numpy\linalg\lapack_lite.pyd" might reveal some more information.

I want to use ModelicaRes to open my Dymola results in python but the import fails.

I tried DyMat and Buildingspy but I would prefer to use ModelicaRes. Because Buildingspy makes use of DyMat which is quiet old and seems unmaintained.
I also had this issue.
I fixed this in my fork of modelicares here: https://github.com/sede-fa/ModelicaRes
I basically replaced any reference to matplotlib.cbook to numpy to get the iterable function as shown here: https://github.com/kdavies4/ModelicaRes/issues/42
You can install this via pip by doing: pip install git+https://github.com/sede-fa/ModelicaRes.git
About a week ago I was able to import tensor flow but now I seem to have a problem running the same code. When I run either of these I am not able to get it to work at this point (what surprises me the most is at least part of it worked last week, now it does not seem to work), I get ImportError: cannot import name 'ClusterDef' which I am not finding anything online on:

ImportError: cannot import name 'ClusterDef'
There is usually two reasons for ImportError
it's circular import attempt
the target object does not exist
in your case i would check if this file really contains ClusterDef class
/anaconda3/lib/python3.6/site-packages/tensorflow/core/protobuf/tensorflow_server_pb2.py
this is dynamically generated protobuf files (by grpc), which could somehow got deleted
in case this file does not contain needed class the best option is probably reinstall tensorflow/anaconda
This is not a duplicate because the linked question does not address how to either locate the required dlls or fix the installation.
I get the following when I try import sklearn v.0.20. I'm using anaconda and both numpy and scipy are up to date.

ImportError: DLL load failed: The specified module could not be found.
EDIT:
I found this thread : https://github.com/numpy/numpy/issues/10965
That mentions a problem related to this.
So it seems the guy there solved his problem by removing both numpy and scipy and reinstalling them. There is a chance your version of scipy for some reason is linked against a MLK version of numpy and that's the reason things don't work.
END OF EDIT
I checked around for your problem and it seems that this is related to the version of numpy you have.
To fix the problem you should install numpy-MLK which is a version on numpy linked against Intel's Math Kernel Library.
You can find it here:
https://pypi.org/project/numpy-mkl/
Just remember to first remove the already existing numpy package.
You can find more info here:
ImportError when importing certain modules from SciPY
and here:
Difference between Numpy and Numpy-MKL?
I'm trying to install h5py on Mac OSX and use it's group and dataset features, but I'm having an issue. On its installation webpage it says the easiest way for beginners to use it on Mac is to install Anaconda, so that's what I did since I would still consider myself an inexperienced programmer. Anyway, after installing Anaconda and typing the following script into iPython Notebook, I get an "image not found error."

Your traceback shows that you are using Canopy's Python, not Anaconda's. Either (1) make sure Anaconda appears in your system path before Canopy or (2) use Canopy's package manager to install h5py. Since you have Canopy installed already, and that's what appears first in your path already, that might be the easiest choice for you. You can either use the graphical Package Manager (reachable from the Welcome screen) or install h5py from the command-line
enpkg h5py
Although this has come up as a topic before it has not been answered. I get the following import error I have just installed canopy from EPD and after I installed it, it keeps coming up with the following error:

Check Canopy's Package Manager. Make sure matplotlib 1.3.1-8 package is installed.
An older version of matplotlib could be installed. Check the updates section and update your canopy.
