运行tensorboard报错:ValueError: Duplicate plugins for name projector

问题描述

模型训练时，查看损失和指标，终端调用tensorboard时报错如下：

(bsrn) D:\All model\GAN Model\Three\BSRN-main\BSRN-main>Tensorboard --logdir=./tb_logger/BSRN_x4

解决方案：

环境里安装了多个版本的tensorboard和tensorflow，按照提示卸载并重新安装：

pip uninstall tb-nightly tensorboard tensorflow tensorflow-estimator tf-estimator-nightly tf-nightly
pip install tensorflow  # or `tensorflow-gpu`, or `tf-nightly`, ...
