I am using PyInstaller version 5.0.dev0 and Python version 3.9.1.
I tried pip3.9 install transformers, pip3.9 install regex, I tried adding hooks hook-regex.py and hook-transformers.py.
I would really appreciate any suggestions! Thank you!
I have some experience starting starting up Apache Airflow but I have now an error when I try to airflow db init command. The error is as below. I am running Airflow on virtual env with Python 3.8. Any help would appreciated. I am not sure to understand this error as I managed to init the db without importing any _cffi_backend module in the past.
The error:

Airflow 2 has hard requirement on cryptography module being installed and operating. So you have to install it properly. There are some distributions of Linux that you need to add some additional packages to make it works.
You can take a look at this query and similar problems and possibly you will find out how cryptography can be installed or reinstalled cleanly.
No module named _cffi_backend
Check the installation docs for cryptography: https://cryptography.io/en/latest/installation/
If you are using Alpine, make sure you install the following:
$ sudo apk add gcc musl-dev python3-dev libffi-dev openssl-dev cargo
Similarly for Debian/buster:
$ sudo apt-get install build-essential libssl-dev libffi-dev \
python3-dev cargo
Check their installation guide for other distros and run airflow db init again

I tried changing some values in config file but no luck! please help me fix this problem
This might help:->
steps include:->
1-open cmd
2-paste the path of your Jupyter folder
3-write "Jupyter notebook" and press enter you will redirect to Jupyter
4-still not working check your python path is configured or not and then go to step1,2,3:->
upvote if it's helpful
or
you can made another folder jupyter folder and then configure python
and install jupyter notebook and use above steps.
I am trying to make a distributable of a flask application. Everything works fine when running locally. When an executable is generated with pyinstaller it gives me the error:
Traceback (most recent call last):
File "site-packages\flask\app.py", line 2446, in wsgi_app
File "site-packages\flask\app.py", line 1951, in full_dispatch_request

File "site-packages\flask\templating.py", line 120, in _render
jinja2.exceptions.TemplateNotFound: bootstrap/base.html
I am using the flask bootstrap as shown here.
create a new python file named 'hook-flask_bootstrap.py', inside of this paste the following:
from PyInstaller.utils.hooks import collect_data_files
datas = collect_data_files('flask_bootstrap')
Now when you run pyinstaller provide the path to this 'hook-flask_bootstrap.py' file:
--additional-hooks-dir=PATH (If relative path, just use .)
I'm taking advantage of the fact that Airflow v1.7.1.3 provides access to airflow.cfg to place some configuration values there rather than embedded in the code. We added the following as the first lines of the airflow.cfg file:
[foo]
bar = foo
bar
In the foobarDAG.py class representing the DAG, I do the following:
from airflow.configuration import conf
…
def fooBar():
pass
foobarList = conf['foo']['bar'].split('\n')
foobarOperator = PythonOperator(
task_id='fooBar',
provide_context=True,
python_callable=fooBar,
op_args=[foobarList],
dag=dag)
Testing this manually from the Python prompt is easy:
>>> from foobarDAG import foobarList
…
>>> foobarList
['foo', 'bar']
That's just what I would expect from the information in airflow.cfg, above.
We've also performed a test on the DAG directly:
airflow test foobarDAG fooBar 10-19-2016
That doesn't report any problems.
The problem crops up when we try to use the scheduler to schedule that one DAG:
airflow scheduler -d foobarDAG >& foobar_log.txt
In the web UI, we see the following at the top of the "DAGS" section:
Broken DAG: [/path/to/…/foobarDAG.py] 'foo'
And in foobar_log.txt, here is the error message:
[2016-10-19 14:56:09,028] {models.py:250} ERROR - Failed to import: /path/to/foobarDAG.py
Traceback (most recent call last):

File "/path/to/anaconda3/envs/foobarenv/lib/python3.5/configparser.py", line 956, in __getitem__
raise KeyError(key)
KeyError: 'foo'
So oddly it appears that the scheduler isn't retrieving the ['foo'] section from airflow.cfg and providing it to the DAG. Any idea why?
It turns out that everything was working properly, but the scheduler hadn't been restarted. The scheduler was apparently still using the old airflow.cfg which did not have the added section.
