由于whl文件找错了 安装包的最新版本
出现自己的包无法调用，并且报错的情况，需要在from前面加
import sys sys.path.append('D:\\文件夹的绝对路径')在windows是使用双斜杠
实现路径下的特定文件复制到特定的地址（其中sor_name目标文件的初始位置，，需要包括地址加文件名,dst_name将文件保存到特定地址，同时也需要添加文件名.后缀）
import shutil sor_name = osp.join(dpath, name) dst_name = osp.join(self.raw_dir, name) shutil.copyfile(sor_name, dst_name)Coverage.py warning: Module test_dropout.py::test_dropout_adj was never imported. (module-not-imported)
在官方手册上看到的，改了一下好像确实运行起来是没问题的
coverage.misc.CoverageException: No data to report.解决方法
from .gcn2_con import GCN2Con.就是./,表示目录层级
pytest test --html=report_2.html --self-contained-html
对test文件夹里面的pytest文件进行测试，然后生成report.html报告文件
