Flet can't run certain libraries #4213

Describe the bug

I'm trying to get scikit-learn to run but it causes an error. All other libraries are running fine. It runs well in my ide but once compiled causes an error. So far I have tested for Windows, android and webapp. The windows is executable when packaged with pyInstaller. Hope this error can be sorted out 1729592055864

Code sample

import flet as flt from sklearn.feature_extraction.text import TfidfVectorizer from sklearn.metrics.pairwise import cosine_similarity import pandas as pd

Function to tokenize the code (a simple example)

def myapp(page: flt.Page):

Initialise page criteria and components

page.theme_mode = flt.ThemeMode.LIGHT
page.window.maximized=True
page.scroll=True

global methods, method1, data1, cl1, runner,allowed
allowed=["py"]
runner = 0
file_picker = flt.FilePicker()
page.overlay.append(file_picker)

# dv = flt.Column([methods], scroll=True)
# meth = flt.Row([dv], scroll=True, expand=1, vertical_alignment=flt.CrossAxisAlignment.START)
# method1 =
data1 = flt.TextField(
    label="Code 1",
    value="""

def factorial(n):
if n == 0 or n == 1: return 1 else: return n * factorial(n - 1)

Example usage

num = 5 result = factorial(num) print(f"The factorial of {num} is {result}")",""", hint_text="eg. 12 14 15 18 24...", helper_text="Original Code", tooltip="Enter integers separated by spaces", multiline=True, width=(page.width-50)/2, ) cl1 = flt.TextField( label="Code 2", value="""
def sum_of_squares(numbers): total = 0 for num in numbers: total += num * num return total

Example usage

nums = [1, 2, 3, 4, 5] result = sum_of_squares(nums) print(f"The sum of squares of {nums} is {result}")""", hint_text="eg. 8", helper_text="Code to be checked", tooltip="Enter a single integer for cache line number", multiline=True, width=(page.width-50) / 2, )

butang = flt.ElevatedButton(text="Run", on_click=lambda e: process())

# methods.horizontal_lines = flt.border.BorderSide(2, "#fdfcff")
page.add(butang)

# Function to compute the plagiarism similarity between two code snippets
def compute_similarity(code1, code2):
    # Tokenize both code snippets
    code1_tokens = code1
    code2_tokens = code2

    # Use TF-IDF Vectorizer to convert code to vectors
    vectorizer = TfidfVectorizer()
    vect_mat=vectorizer.fit_transform([code1_tokens, code2_tokens])
    print("TF-IDF Vocabulary:")
    print(vectorizer.vocabulary_)
    df = pd.DataFrame(vectorizer.transform([code1_tokens, code2_tokens]).toarray(), columns=vectorizer.get_feature_names_out())
    print(df)
    # Compute the cosine similarity between the vectors
    similarity_matrix = cosine_similarity(vect_mat)
    print(similarity_matrix)
    return similarity_matrix[0][1]  # Returns the similarity score between code1 and code2

def process():
    row=0
    mastlst=[]
    tbllst = []
    for i in range(2):
        for j in range(i + 1, 2):
            tbllst.insert(0,"Code 1")
            tbllst.insert(1,"Code 2")
            #Compare logic TFIDF
            similarity_score=compute_similarity(data1.value, cl1.value)
            print(f"Plagiarism Similarity Score: {similarity_score:.2f}")
            tbllst.insert(2,round(similarity_score, 2))
            print(row)

    mastlst.append(tbllst)
    page.update()

Can you please re-format your code sample for readability, and also try this sample with the latest Flet release?

I have updated the codes to only the parts where sk-learn is used and updated flet to the latest version (0.24.1). The issue still persists
