1.DSMIL方法
(1).AttributeError: ‘version_info’ object has no attribute ‘version’
解决办法： pip install pyparsing==2.4.7
(2).解决GPU上运行pytorch代码的错误
python: symbol lookup error: /home/daichuangchuang/anaconda2/envs/dsmil/lib/python3.6/site-packages/torch/lib/libtorch_python.so: undefined symbol: PySlice_Unpack
解决办法：
a.首先原有的环境：pip freeze>requirements.txt
b.创建一个新的环境：conda create -n DSMIL python==3.6.2
c.激活新建的环境：conda activate DSMIL
d.安装原有环境中的所有包：pip install -r requirements.txt
e.原有的错误问题的得到解决。
(3).torch版本问题

解决方法：
pip install torch==1.8.0 pip install torchvision==0.9.0
(4).运行错误
RuntimeError: CUDA error: CUBLAS_STATUS_INTERNAL_ERROR when calling cublasCreate(handle)
解决办法：需要重新安装对应的版本：
具体命令：
pip install torchvision==0.8.2 pip install torch==1.7.1
