mmcls 支持 base64 数据输入嘛🐎？

[TPL-egg-HIT]

mmcls支持base64数据作为输入嘛，我看了官方文档，也找到了如下的代码
mmcv/fileio/file_client.py
我的结论是目前不支持base64作为输入，那我需要怎么修改代码呢，谢谢～

You can modify the LoadImageFromFile transformer. use base64 to decode the stream. notice this line.

import base64

img = base64.b64decode((img_bytes))

fro the detail, please refer to https://www.codespeedy.com/convert-base64-string-to-image-in-python/

THANKS~
It seems that, I need to define a new func to support base64,
and change
try:
if self.file_client_args is not None:
file_client = fileio.FileClient.infer_client(
self.file_client_args, filename)
img_bytes = file_client.get(filename)
else:
img_bytes = fileio.get(
filename, backend_args=self.backend_args)
img = mmcv.imfrombytes(
img_bytes, flag=self.color_type, backend=self.imdecode_backend)
except Exception as e:
to :
try:
img = mmcv.imfrombytes(
img_bytes, flag=self.color_type, backend=self.imdecode_backend) # imdecode_backend - I need to define a new name.
except Exception as e:

just replace this line :

img = mmcv.imfrombytes(img_bytes, flag=self.color_type, backend=self.imdecode_backend)
