I'm currently trying to change the looks of the nbconvert-output in jupyter. To be more precise, I want to convert a ipynb to latex but not using the default tamplate. The thing is I don't know how to edit the files to get the result I want.
Lets say I want to use the "style_notebook.tplx" so I need to donwload ipython_nbconvert_config.py and use_cell_style.tplx. After that I need to change in the use_cell_style file the second line to ((* set cell_style = 'style_notebook.tplx' *)). But to be honest I don't know with what to edit a .tplx File (I used just Editor from Windows)....
After changing that and moving the two files to the same directonary as my .ipynb is, I tried this in the command prompt:
jupyter nbconvert --config ipython_nbconvert_config --to latex filename.ipynb
and got the error:
[NbConvertApp] WARNING | Error loading config file: ipython_nbconvert_config

So it says that I miss the PDF-module, but I'm not sure hows that possible, because until now I could convert to pdf just fine. So I aussume I made some mistakes in changing the files...
Would be nice if someone could explain how to fix this problem..
Thanks, Sito.

I am developing a code where I need to create a Manager to synchronize a Queue. In the project I am using hydra and everything works fine until I create a multiprocessing Manager Object. This is the raised error with HYDRA_FULL_ERROR=1:
Primary config module 'config' not found.
Check that it's correct and contains an __init__.py file
Set the environment variable HYDRA_FULL_ERROR=1 for a complete stack trace.

Check that it's correct and contains an __init__.py file
I also attach a minimal code snippet to reproduce the error.
import hydra
from multiprocessing import Manager
#hydra.main(config_path='config', config_name='config')
def main(cfg):
m = Manager() # The error is in this line
m.Queue()
main()
The config.yaml is correctly created and located since when I don't use the Manager, the entire code works with no errors:
- PROJECT ----- config ---- config.yaml
|
|
----- main.py
As far as I have understood, the problem comes from the fact that hydra changes the directory when initialized and afterwards, when the Manager is created, hydra is called again to be initialized but as the directory has been changed, it can not find the config folder. If this is true, is it a bug or can it be solved?
Thank you so much for your help.
I'm not able to reproduce the error on my machine.
You can stop hydra from changing directories at runtime by passing hydra.job.chdir=False at the command line -- see the docs on how to disable changing current working dir to job's output dir.
python main.py hydra.job.chdir=False
I have referred to this tut to get started with pyspark on windows. These are the steps I followed:
Downloaded spark prebuilt for hadoop 2.7 from here
Extracted spark-2.1.0-bin-hadoop2.7.tgz to the directory set as %SPARK_HOME% in environment variables
Downloaded winutils.exe from here
Pasted winutils.exe in %SPARK_HOME%\bin
Set %HADOOP_HOME% to same directory as %SPARK_HOME%
Set %PYSPARK_DRIVER_PYTHON% to ipython
Set %PYSPARK_DRIVER_PYTHON_OPTS% to notebook
Added ;%SPARK_HOME%\bin to %PATH%
But when I run
> pyspark --master local[2]
I get following error:
[TerminalIPythonApp] WARNING | Subcommand `ipython notebook` is deprecated and will be removed in future versions.
[TerminalIPythonApp] WARNING | You likely want to use `jupyter notebook` in the future

I believe my issue is some missconfiguration of my windows spark environment. Thats why I gave all above information. So whats going wrong here?
Note that I performed the steps without using Anaconda and GOW (Gnu on windows) as suggested in the tut.
Point your %PYSPARK_DRIVER_PYTHON% to a virtual environment with all dependencies including 'Poller' and then check.
Else you can try installing 'Poller' in ipython environment( which I frankly dont know how!)

I'm using Python 2.7 with SQLAlchemy.
I'm trying to see if I can use Dogpile.Cache.
I've installed dogpile cache using
pip install dogpile.cache
but when I try to run the example given by SQLAlchemy (helloworld.py)
I keep getting ImportError: No module named fcntl. I thought the newest Dogpile.Cache resolved the windows issue...
Could someone please help?
Thank you.
UPDATE
Ok, the example is creating the database and cache. But when it is trying to load data using FromCache it is giving me an error.

ValueError: Could not determine directory that contains both, this file and lib/ipaddr.
It's a correct error coming from dev_appserver.py... there is no lib/ipaddr in the /usr/local/bin directory.
Why is nosetests triggering the raising of this error? Why does dev_appengine try to look for lib/ipaddr in the first place?
