Python 脚本无法在我的计算机上运行特定文件

Question

I'm using Python 3.7 and learning on a published code. In my first attempt to write the code, it ran without errors which means all of the necessary libraries (NumPy, Pandas, scikit-learn) should have been installed properly by me. When I changed the source file in order to work on different data, it stopped working. However, it works on another computer. I updated the system with all of the apps and tried to shorten the imported file, but it didn't change anything. The input files are identical on both computers.

This is the error with warnings:

This is the code:

import numpy as np
import matplotlib.pyplot as plt
import pandas as pd

data=open("./data3.csv")

headernames=data.readline()
dataset=pd.read_csv("data3.csv")
dataset.head()

X = dataset.iloc[:, :-2].values
y = dataset.iloc[:, -1].values

from sklearn.model_selection import train_test_split
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size = 0.30)

from sklearn.ensemble import RandomForestClassifier
classifier = RandomForestClassifier(n_estimators = 50)
classifier.fit(X_train, y_train)

y_pred = classifier.predict(X_test)

from sklearn.metrics import classification_report, confusion_matrix, accuracy_score
result = confusion_matrix(y_test, y_pred)
print("Confusion Matrix:")
print(result)
result1 = classification_report(y_test, y_pred)
print("Classification Report:",)
print (result1)
result2 = accuracy_score(y_test,y_pred)
print("Accuracy:", result2)

Answer 1

Are you using the imp module in your code? Like import imp ?
If so, can you try using import importlib .

Also, I see warnings related to collections .
Try to check the answer provided in this SO answer

Apart from these, you have an error of
ValueError: Input contains NaN, infinity or a value too large for dtype('float64').
You might have to take a look at your input file once again. It seems there are issues with the input.
