Hi everyone! I am trying to publish my streamlit app and am running into the error:

PermissionError: [Errno 13] Permission denied: '/mount/src/fireoccurrenceprediction/lightning/weather/cf-build-AB.exe'During handling of the above exception, another exception occurred:Traceback (most recent call last):  File "/usr/local/lib/python3.9/multiprocessing/pool.py", line 125, in worker    result = (True, func(*args, **kwds))  File "/mount/src/fireoccurrenceprediction/Home.py", line 147, in runHumanFOPModel    raise Exception(e)Exception: [Errno 13] Permission denied: '/mount/src/fireoccurrenceprediction/lightning/weather/cf-build-AB.exe'"""The above exception was the direct cause of the following exception:Traceback (most recent call last):  File "/mount/src/fireoccurrenceprediction/Home.py", line 356, in run_human_fop_model    result.get()  File "/usr/local/lib/python3.9/multiprocessing/pool.py", line 771, in get    raise self._valueException: [Errno 13] Permission denied: '/mount/src/fireoccurrenceprediction/lightning/weather/cf-build-AB.exe'

My code uses a mix of python and C files and I am attempting to call the C executable cf-build-AB.exe which is raising the permission error.

Here is a link to my App Link

And this is my code:

In Home.py

from lightning import LightningFireOccurrencePrediction
from human import HumanFireOccurrencePrediction

And then in the HumanFireOccurrencePrediction Class

        self.weather_interpolation_exe_path = \

        self.weather_binning_exe_path = \

Hello I am having the following error on my published streamlit App:

PermissionError: [Errno 13] Permission denied: '/mount/src/fireoccurrenceprediction/lightning/weather/cf-build-AB.exe'During handling of the above exception, another exception occurred:Traceback (most recent call last):  File "/usr/local/lib/python3.9/multiprocessing/pool.py", line 125, in worker    result = (True, func(*args, **kwds))  File "/mount/src/fireoccurrenceprediction/Home.py", line 147, in runHumanFOPModel    raise Exception(e)Exception: [Errno 13] Permission denied: '/mount/src/fireoccurrenceprediction/lightning/weather/cf-build-AB.exe'"""The above exception was the direct cause of the following exception:Traceback (most recent call last):  File "/mount/src/fireoccurrenceprediction/Home.py", line 356, in run_human_fop_model    result.get()  File "/usr/local/lib/python3.9/multiprocessing/pool.py", line 771, in get    raise self._valueException: [Errno 13] Permission denied: '/mount/src/fireoccurrenceprediction/lightning/weather/cf-build-AB.exe'

My code contains both C and Python files. I am attempting to use my executable C file cf-build-AB.exe but am getting a permission error. Note that the code works locally just not on the published App.

I get the error in the following code:

Hi Everyone! I am trying to publish my streamlit App and am running into the error

PermissionError: [Errno 13] Permission denied: '/mount/src/fireoccurrenceprediction/lightning/weather/cf-build-AB.exe'During handling of the above exception, another exception occurred:Traceback (most recent call last):  File "/usr/local/lib/python3.9/multiprocessing/pool.py", line 125, in worker    result = (True, func(*args, **kwds))  File "/mount/src/fireoccurrenceprediction/Home.py", line 147, in runHumanFOPModel    raise Exception(e)Exception: [Errno 13] Permission denied: '/mount/src/fireoccurrenceprediction/lightning/weather/cf-build-AB.exe'"""The above exception was the direct cause of the following exception:Traceback (most recent call last):  File "/mount/src/fireoccurrenceprediction/Home.py", line 356, in run_human_fop_model    result.get()  File "/usr/local/lib/python3.9/multiprocessing/pool.py", line 771, in get    raise self._valueException: [Errno 13] Permission denied: '/mount/src/fireoccurrenceprediction/lightning/weather/cf-build-AB.exe'

My code uses a mix of python and C files and the error is raised when I call the executable cf-build-AB.exe (which is the exe of my C file) in my code. If anyone has any ideas of why this error is occurring the help would be greatly appreciated!
