Problem receiving inputs in pyqt5 and performing learning machine operations on it

Question

I want to take all the inputs of this and when I press the button, it will use these inputs for me as input for random forest operations, but when I press the button, the program will be interrupted.

for do this I use pyqt5 and sk-learn RandomForest

I want to get the inputs floating and use it to predict the machine learning system trained in the random forest method and display the result of my system forecast on the screen and the text that fits the forecast below. Show it but I do not know pyqt5 Help us if possible

Please see the image: my pyqt5 output

import pandas as pa
from PyQt5.QtWidgets import QWidget
from sklearn import ensemble
from sklearn.model_selection import train_test_split

data = pa.read_csv("data.csv")
y = data['Score']
x = data.drop(["name", "Score"], axis=1)
x_train, x_test, y_train, y_test = train_test_split(x, y, test_size=0.20)

Forest = ensemble.RandomForestRegressor()
RandomForest = Forest.fit(x_train, y_train)
# print(RandomForest.score(x_train, y_train))
