I am trying to add Persian language to spaCy. I followed almost everything which was said here. But when I issue the below command
python -m spacy train fa fa-model fa-ud-train.json fa-ud-dev.json --n-iter 25 --no-ner
I get some errors that I don't know how to fix.
$ python -m spacy train fa fa-model fa-ud-train.json fa-ud-dev.json --n-iter 25 --no-ner

I'm using the AWS CDK to run lambda functions locally. I have followed a couple of tutorials on setting this up but I appear to be getting issues when invoking the function with SAM. The typical error I encounter is below:

I've had multiple errors similar to that above but sometimes the file that is (apparently) missing is different. It looks like an issue with building the image rather than the stack code itself but I'm unsure and couldn't find any other similar issues.
The code I am using in the Stack class object is below:
pypass_lambda_layer = _lambda.LayerVersion(self, "PypassLambdaLayer", code=_lambda.Code.from_asset("lambda/layers"), compatible_runtimes=[_lambda.Runtime.PYTHON_3_9])
my_lambda = _lambda.Function(self, "Pypasshandler", runtime=_lambda.Runtime.PYTHON_3_9, code=_lambda.Code.from_asset("lambda/code"), handler="handler.handle", layers=[pypass_lambda_layer])
Tutorials I tried to follow:
https://dev.to/upupkenchoong/how-to-provision-lambda-and-lambda-layer-with-cdk-2ff4
https://medium.com/geekculture/deploying-aws-lambda-layers-with-python-8b15e24bdad2
The layers folder referenced in the LayerVersion function contains another folder called python which has pandas installed in it.
\lambda
\layers
\python

handler.py
I'm on a windows machine and I have the cdk packages installed in conda virtual environment.
Any help would be greatly appreciated.
Thanks

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

ModuleNotFoundError: No module named 'PDF'
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'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.
