from tensorboardX import SummaryWriter 仅在第二次工作

Question

在 ipython 如果我这样做：

from tensorboardX import SummaryWriter

我收到一长串错误（如下所示）。

但如果我再做一次，我就不会出错。这是为什么？

错误：

Answer 1

看看升级模块是否有帮助..

pip install --upgrade tensorboardX

或

因为这个库在我这边是没有问题的，所以试试这个

try:from tensorboardX import SummaryWriter
except:from tensorboardX import SummaryWriter

Answer 2

希望对您有所帮助。通过搜索“Couldn't build proto file into descriptor pool”

得到

pip uninstall protobuf
pip install --no-binary=protobuf protobuf
