我收到错误“ImportError：没有名为Tkinter的模块，但不知道为什么。
当我运行我的脚本，我得到这个错误，但这通常是做一个库，你试图使用，你还没有进口。我已经搜索过了，我发现的所有帖子都与某人直接相关，或者没有以正确的方式导入库。我已经在ubuntu 14.04、Spyder和Cloudera数据科学工作台上从命令行运行了这个脚本，它运行得很好。在所有这些机器上，我都没有导入库，它工作得完美无缺。
当我尝试在我的rhel 7机器上运行它时，我得到以下错误：

字符串
当它点击“import matplotlib.pyplot as plt”时，似乎会出现错误。
这些是我正在使用的库，在其他任何地方都可以正常工作：

#Libraries
import pandas as pd
import numpy as np
import hashlib
import matplotlib.pyplot as plt
from sklearn.preprocessing import LabelEncoder, OneHotEncoder
from sklearn.model_selection import train_test_split
from sklearn.preprocessing import StandardScaler
import keras
from keras.models import Sequential
from keras.layers import Dense
from sklearn.metrics import confusion_matrix
