如何啟動tensorboard以及可能會面臨到的問題 (Pytorch)

1. 安裝

conda install tensorboard

2. 啟動 & 面臨問題

啟動tensorboard會出現 Numpy版本超過2.0會有問題

(pytorch) C:\Users\KJ.Chang\Desktop\code\YOLOv1>tensorboard --logdir=runs 
Traceback (most recent call last):

    raise AttributeError(
AttributeError: `np.string_` was removed in the NumPy 2.0 release. Use `np.bytes_` instead. 

3. 解決辦法

先解安裝numpy

conda uninstall numpy

安裝numpy小於2.0的版本，我這邊選擇安裝1.26.0版

conda install numpy==1.26.0

再次安裝tensorboard

conda install tensorboard

4. 再次啟動

啟動後點擊以下網址即可打開Tensorboard

(pytorch) C:\Users\KJ.Chang\Desktop\code\YOLOv1>tensorboard --logdir=runs
