Python Minecraft Launcher Lib File Not Found Error

I wanted to create a Minecraft Launcher using Python today, but the game cannot be started.
My Code:
import minecraft_launcher_lib
import subprocess
minecraft_directory = "C:\\Users\\Mert KAPLANDAR\\AppData\\Roaming\\.minecraft"
options = minecraft_launcher_lib.utils.generate_test_options()
minecraft_command = minecraft_launcher_lib.command.get_minecraft_command("1.8.9", minecraft_directory, options)
subprocess.call(minecraft_command)
Error:
Traceback (most recent call last):
File "C:\Users\Mert KAPLANDAR\Desktop\launcher.py", line 10, in <module>
subprocess.call(str(minecraft_command))

#Mert Kaplander, I would believe the error might be because you don't have that version of Minecraft installed. You can check with the following method:
minecraft_launcher_lib.utils.get_installed_versions(minecraft_dir)
example:
import subprocess
import minecraft_launcher_lib
from colorama import Fore, init
for version in minecraft_launcher_lib.utils.get_installed_versions(minecraft_dir):
print(Fore.GREEN+ f"{version}")
Other than that, your code is an exact copy from the documentation. So I don't see an other error.

Pyflink get_gateway() method is not working

I am using PyCharm to run simple pyflink latest 1.13 example (it is only two lines). But the get_gateway() method is not working.
For the interpreter I created virtual environment and use it in my PyCharm project. I also downloaded Java8.
I tried many steps to solve the issue but
from pyflink.common.serialization import Encoder

def print_hi(name):
# Use a breakpoint in the code line below to debug your script.
print(f'Hi, {name}') # Press Ctrl+F8 to toggle the breakpoint.
env = StreamExecutionEnvironment.get_execution_environment()
env.set_parallelism(1)

Setup Selenium & Python on Eclipse FileNotFoundError: [WinError 2]

I'm trying to setup Selenium with Python and Eclipse on my home computer but I keep getting the following 2 trace back errors. I know part of it is that the "geckodriver.exe" file is not in the correct path but I don't know where to move it to so its correct and what the "FileNotFoundError: [WinError 2] The system cannot find the file specified" error refers to.

forced alignment with aneas

I am trying to build a simple dataset for speech recognition using aneas, following the instruction here. However I'm stuck at the forced alignment, here is my code
from aeneas.executetask import ExecuteTask
from aeneas.task import Task
import os
import numpy
config_string = "task_language=eng | is_text_type=plain | os_task_file_format=json"
task = Task (config_string=config_string)
task.audio_file_path_absolute = "D:/documents/AI/open_door.mp3"
task.text_file_path_absolute = "D:/documents/AI/open_door.txt"
task.sync_map_file_path_absolute = "D:/documents/AI/syncmap.json"
ExecuteTask(task).execute()
task.output_sync_map_file()
Which gives the following error:

Intuitively, I think it is because of the file paths, but changing it doesn't seem to work. I have never worked with python before so show me where I did wrong. Thank you.

I'm pretty sure it's because ffprobe isn't in your system's environmental variables.
Have you tried running python -m aeneas.diagnostics and is ffprobe in your path? Look into adding programs to your Path/system environment variables.

FileNotFoundError: [WinError 2] The system cannot find the file specified while trying to use pysndfx

I'm trying to sound process a wav file with python and pysndfx but getting this weird error. I've tried many different path formats and many different paths. Even thought os.path.isfile() returns true it still comes up with this error. Any help would be greatly appreciated.
from pysndfx import AudioEffectsChain
import os
in_file = os.getcwd() + "\\" + "a.mp3"
in_file = in_file.replace("\\", "//")#tried many things here, tried to it without any replacing
if os.path.isfile(in_file):
print("fileyes") #This returns true
else:
print("not a file")
print(in_file)
fs = 44100
fx = (AudioEffectsChain().
reverb().
delay().
phaser()
)
fx(in_file,"apro.mp3")
Here's the error
fileyes

I can't comment (yet) so i'll ask here. Do you have your file in the same directory (folder) as the python program? If not then it won't work even if the file does actually exist somewhere. Try to copy or move both your file and program code into a new/the same folder.
