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:

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 have a python script which is basically a graphic interface (pysimpleguy) to a mysql database.
I am working in python 3.8; my dependencies are:
PySimpleGUI 4.55.1
sqlalchemy 1.3.20
pymysql 1.0.2
pandas 1.1.3
regex 2020.10.15
pillow 8.0.1
The code works and I'd like to compile it to .exe to distribute it to users in my organization.
I tried to compile it with:
pyinstaller -D .\db_interface_v3.6.1_release.py --debug=imports
However, pyinstaller throws some errors when compiling:

If I try to run the compiled exe, I get an error regarding a specific .dll:

Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll.
If I take this missing .dll from my Anaconda environment and copy it into the program's folder, when I try to run the .exe again it just dies without further messages:
import 'numpy.ma' # <pyimod03_importers.FrozenImporter object at 0x000001F6A455BEE0>
PS C:\Users\Spit\Desktop\DIPEx db parser\dist\db_interface_v3.6.1_release>
Any idea on how to sort it out?
Thanks!
Sorted out. As a future reference if someone stumbles upon this question, the error is caused by Windows' PATH_MAX limitation, preventing pyinstaller to find all the necessary files.
In order to disable said limitation: https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=cmd

I am trying to build an executable with pyinstaller and I am getting the following errors:

Try: pip install transformers -U or pip install -e '.[dev]' if you're working with git master
[30391] Failed to execute script 'chatbot2' due to unhandled exception!
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'm having an issue with the loading of a file from dagster code (setup, not pipelines). Say I have the following project structure:
pipelines
-app/
--environments
----schedules.yaml
--repository.py
--repository.yaml
When I run dagit while inside the project folder($cd project && dagit -y app/repository.yaml), this folder becomes the working dir and inside the repository.py I could load a file knowing the root is project
# repository.py
with open('app/evironments/schedules.yaml', 'r'):
# do something with the file
However, if I set up a schedule the pipelines in the project do not run. Checking the cron logs it seems the open line throws a file not found exception. I was wondering if this happens because the working directory is different when executing the cron.
For context, I'm loading a config file with parameters of cron_schedules for each pipeline. Also, here's the tail of the stacktrace in my case:
File "/home/user/.local/share/virtualenvs/pipelines-mfP13m0c/lib/python3.8/site-packages/dagster/core/definitions/handle.py", line 190, in from_yaml

with open(path) as f:
FileNotFoundError: [Errno 2] No such file or directory: 'app/environments/schedules.yaml'
You could open the file using the absolute path of the file so that it opens correctly.
from dagster.utils import file_relative_path
with open(file_relative_path(__file__, './environments/schedules.yaml'), 'r'):
# do something with the file
All file_relative_path is simply doing the following, so you can call the os.path methods directly if you prefer:
def file_relative_path(dunderfile, relative_path):
os.path.join(os.path.dirname(dunderfile), relative_path)

Some friends say：
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:
I use command line:
**pyinstaller -D --i icon\crawler_spider72.ico --additional-hooks-dir hook-flask_bootstrap.py run.py**
I searched for some answers, but after using, there was no action collected. Don't know where the mistake is. Ask the knowledgeable person for advice. Thank you
I've just reinstalled rpy2 with Python3.5 and I am having difficulty figuring out why the module cannot find the "R-Home". I have installed R on my computer already. Should I try reinstalling R or another method? Some help would be much appreciated here!

raise child_exception_type(errno_num, err_msg)
FileNotFoundError: [Errno 2] No such file or directory: 'R'
This means that there is no executable in the PATH when python is calling "R RHOME" in a subprocess.
To overcome this add the path to R to your PATH. For example:
export PATH=/usr/local/some/place/bin:${PATH}
