from tensorboardX import SummaryWriter only works the second time

Question

In ipython if I do:

from tensorboardX import SummaryWriter

I get a long list of errors (shown below).

But if I do it again I get no errors. Why is this?

Errors:

Answer 1

See if upgrading the module would help..

pip install --upgrade tensorboardX

Or

As this library is imported with no issues in my side, then Try this

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

Answer 2

Hope it helps. By searching for "Couldn't build proto file into descriptor pool"

got

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