protobuf not compatiable about visualdl HOT 2 OPEN

要不降低一下visualdldl的版本吧，因为现在visualdl里面对于protobuf的版本就是为了支持paddlepaddle的升级，我理解paddlepaddle之后2.5的版本就是会>=3.20

from visualdl.

依赖问题就像俄罗斯套娃一样，一个接着一个。

降级了版本 pip install visualdl==2.4.2

可以运行，执行demo时，又提示numpy.float版本在1.20后废弃了，默认安装的numpy==1.24.3。

visualdl 2.4.2 还在使用numpy.float（代码在 base_compnent.py引用 labels.astype(np.float) ）

好吧，降级numpy==1.19.5

结果build wheel编译不了...

setup.py:67: RuntimeWarning: NumPy 1.19.5 may not yet support Python 3.10.

哈哈。。。

Fine，查了一下 https://pypi.org/project/paddlepaddle/ 对各系统的支持，原来macOS才支持到python3.8

MacOS version 10.11/10.12/10.13/10.14 (64 bit) (not support GPU version yet)

Python version 2.7.15+/3.5.1+/3.6/3.7/3.8 (64 bit)

pip or pip3 version 9.0.1+ (64 bit)

然后，有依赖cv2，也没有放到依赖定义里。

File "/xxx/lib/python3.8/site-packages/visualdl/utils/img_util.py", line 81, in merge_images
import cv2
ModuleNotFoundError: No module named 'cv2'

有些兼容的依赖不管了，只要能运行，带病上阵跑通了。
