错误:
Traceback (most recent call last):
File "I:/Papers/consumer/codeandpaper/RegressionandGBDTandLR
ValueError: I/O operation on closed file
将代码:
for line in f: print("每一行的数据是:%s" % line) f.close() 改为 for line in f: print("每一行的数据是:%s" % line) f.close() 就可以了。
因为:原来的时候在for循环里进行了close,所以出错
错误:
Traceback (most recent call last):
File "C:/Documents and Settings/Administrator/Desktop/zyx", line 12, in <module>
将代码:
“No module named 'matplotlib.pyplot'; 'matplotlib' is not a package”
脚本文件名写成了“matplotlib.py',导致pycharm不能加载正确的包。。。。
