Seaborn的Python庫在Visual Studio中無法正常工作

Question

我試圖在Visual Studio中運行包含Python庫matplotlib和seaborn的Python腳本。 包含matplotlib的腳本只能正確運行並顯示繪圖，但是，包含seaborn的腳本不會執行任何操作（無錯誤）。 我通過安裝Anaconda安裝了庫。

正常工作的代碼是來自matplotlib網站的示例：

"""
========
Barchart
========

A bar plot with errorbars and height labels on individual bars
"""
import numpy as np
import matplotlib.pyplot as plt

N = 5
men_means = (20, 35, 30, 35, 27)
men_std = (2, 3, 4, 1, 2)

ind = np.arange(N)  # the x locations for the groups
width = 0.35       # the width of the bars

fig, ax = plt.subplots()
rects1 = ax.bar(ind, men_means, width, color='r', yerr=men_std)

women_means = (25, 32, 34, 20, 25)
women_std = (3, 5, 2, 3, 3)
rects2 = ax.bar(ind + width, women_means, width, color='y', yerr=women_std)

# add some text for labels, title and axes ticks
ax.set_ylabel('Scores')
ax.set_title('Scores by group and gender')
ax.set_xticks(ind + width / 2)
ax.set_xticklabels(('G1', 'G2', 'G3', 'G4', 'G5'))

ax.legend((rects1[0], rects2[0]), ('Men', 'Women'))


def autolabel(rects):
    """
    Attach a text label above each bar displaying its height
    """
    for rect in rects:
        height = rect.get_height()
        ax.text(rect.get_x() + rect.get_width()/2., 1.05*height,
                '%d' % int(height),
                ha='center', va='bottom')

autolabel(rects1)
autolabel(rects2)

plt.show()

如果我運行代碼：

# First, we'll import pandas, a data processing and CSV file I/O library
import pandas as pd

# We'll also import seaborn, a Python graphing library
import warnings # current version of seaborn generates a bunch of warnings that we'll ignore
warnings.filterwarnings("ignore")
import seaborn as sns
import matplotlib.pyplot as plt
sns.set(style="dark", color_codes=True)

# Next, we'll load the Iris flower dataset, which is in the "../input/" directory
iris = pd.read_csv("Iris.csv") # the iris dataset is now a Pandas DataFrame

# Let's see what's in the iris data - Jupyter notebooks print the result of the last thing you do
iris.head(1000)

# Press shift+enter to execute this cell

在Visual Studio中什么也沒有發生，但是在

給出正確的輸出。

我如何才能在Visual Studio中獲得完美的工作？

Answer 1

您在這里比較兩個完全不同的代碼。 第一個代碼在新窗口中生成圖。 第二個代碼沒有任何輸出。 正如代碼中的注釋所指出的那樣，“ Jupyter筆記本打印出您所做的最后一件事的結果”。

Visual Studio不會這樣做； 或更籠統地說，python不會這樣做。 如果要在python中打印某些內容，則需要print語句或函數。

在python 2中，執行

print iris.head(1000)

在python 3中執行

print (iris.head(1000))

所有這些與seaborn無關。
