I would like to save a python plot. With MacOS everything runs smoothly but it fails under Windows7.
The python-command looks like this:
savefig('C:\Users\xyz\AppData\Local\Temp\pyplot1468046843481608342.png')
The error messge is this one:
Traceback (most recent call last):
File "C:\Users\xyz\AppData\Local\Temp\analyze3744796441786382480.py", line 340, in <module>

IOError: [Errno 22] invalid mode ('wb') or filename: 'C:\\Users\xyz\\AppData\\Local\\Temp\\pyplot1468046843481608342.png'
This is the Python I'm using:
Python 2.7.8 :: Anaconda 2.1.0 (32-bit)
Can anybody explain the cause of the problem?
I think you have to add r before your directory to convert your string into raw string. See this post
Unknown python expression filename=r'/path/to/file'

Upgraded MetPy to 1.1 and my ability to produce satellite images from a THREDDS server is no longer working. I isolated the part that is causing me issues.
Example:
#!/usr/bin/python3
import metpy
from siphon.catalog import TDSCatalog
cat_e = TDSCatalog('https://thredds.ucar.edu/thredds/catalog/satellite/goes/east/products/CloudAndMoistureImagery/FullDisk/Channel09/current/catalog.xml')
nc_e = cat_e.datasets[0].remote_access(use_xarray=True)
data_e = nc_e.metpy.parse_cf('Sectorized_CMI')
yields the following output/error

I appreciate any thoughts on how to get around this.
Can you double check that your Python installation with MetPy is correct? I was able to run your code fine on my local install of MetPy 1.1.0 with Python 3.9. Also, your traceback shows Python 3.6 being used; MetPy 1.1.0 only supports Python >=3.7. You should not have been able to install MetPy 1.1.0 with that version of Python.
You can confirm the version of MetPy being used by adding the following to your script:
print(metpy.__version__)
I'm trying to install devstack in my RHEL 7 VM. Earlier everything went good. But while installing the nova, its throwing the following error. How can i resolve this. Should i need to change the code in all the trace back files or any python package/module is available which can resolve this issue? I don't think it's a good idea to change the code in the mentioned files. Is there any way to proceed further.(The python version is 2.7)

I am currently trying to open a large file on my 64 bit Mac (using 64 bit Miniconda, as this is the only version for mac). I use a framework 'sumatra' which is a library to track scientific computing work and possibly reproduce it. I get the following error. I was able to debug a little, and found out that it is mainly due to X_train.npy being too big (3.6GB when not unpacked).

Any experience resolving such issues? Where should I look further? Any ideas?
I downloaded the ansible-2.0.0-0.2.alpha2.tar.gz and installed it on my control machine. However now I'm not able to ping any of my machines. Previously using v1.9.2 i could communicate with them. Now it gives the following error:

Any help would be appreciated.
This is a known bug due to some Unicode changes made to the playbook parser in 2.0. Several versions of Python shipped with a version of shlex.split() that fails horribly on Unicode input- you likely have one of them installed. The bug has been worked around and will be included in the next drop. See https://github.com/ansible/ansible/issues/12257
I'm trying to import GTK in Ubuntu Python 2.7, and I get the following error. PyGTK imports just fine. When I import gtk, I get the following error:

TypeError: idle_formatwarning() got an unexpected keyword argument 'file'
How do I fix this?
This is a bug in idle. Looking at the last line of that error message:
File "/usr/lib/python2.7/idlelib/PyShell.py", line 64, in idle_showwarning
lineno, file=file, line=line))
TypeError: idle_formatwarning() got an unexpected keyword argument 'file'
This is saying that the warning.idle_showwarning method does not have an argument "file".
Sure enough looking at /usr/lib/python2.7/warnings.py
def formatwarning(message, category, filename, lineno, line=None)
There is no such argument.
This apparently has been resolved in source control but I do not think it has made it into a release yet. I would just hack the /usr/lib/python2.7/idlelib/PyShell.py file and remove the offending argument from line 64.
Then try it again...
Try it outside of IDLE. The error here is in IDLE, not your code.
Create a new script that contains import gtk and save it anywhere.
From the command line, in the directory where your script is located, run python whatever_your_scripts_name_is.py.
See if you get an error. You may not be able to import gtk in IDLE.
Edit: There is apparently a problem with GTK and IDLE in some situations on Ubuntu.
Try a different Python shell; I'd recommend IPython which you can install with Synaptic or sudo apt-get install ipython.
