is_test is not correctly set in EfficientNet, leading to drop_connect in test time. It can be easily reproduced by a repeat of inferring in the same image, like what happens in the following.

The predicted probabilities were different between different runs.

The cause may like this.

is_test defaults to False in EfficientNet and is not being set to True in either infer.py or predict.py.

Moreover, duplicated definition of is_test in both __init__ and net leads to confusion.

In fact, _drop_connect uses self.is_test and is_test passed by methods is not used.

It would be better to fix it.

paddle版本：1.7.1
config: ResNet50_vd.yaml
执行训练后出错：

resnet50_vd init中确实没有is_test字段，但是program.create_model中会传入这个字段：

请问下这里是我的版本问题吗？

想请问下，能否单独导出trt引擎文件，希望更灵活的使用trt模型，比如deep stream。

其他接口也是，基本没有参数说明

Mixed precision training is available in PaddleCV/image_classification but not in this repo. According to Release Notes of PaddlePaddle 1.7, AMP interfaces have been added.

Based on these, I think it would be convenient to implement it.

Mixed precision training is critical to fast training on V100. Please consider adding it. Thank you!

although we support workable running scripts, some mistakes always happen when users try to run their own script without export PYTHONPATH

• import ppcls by the relative path

您好，我用infer脚本进行推断的时候遇到了如下的问题
第一次infer：class id: 1, probability: 0.9075
第二次infer：class id: 1, probability: 0.9048
第三次infer：class id: 1, probability: 0.9069

这是我的运行脚本：
export PYTHONPATH=$PWD:$PYTHONPATH
export CUDA_VISIBLE_DEVICES=0
#--model=EfficientNetB0 --pretrained_model=output/EfficientNetB0_val/best_model_in_epoch_124/ppcls --output_paht=./convert
python tools/infer/infer.py
--image_file=./tools/img.jpg
--model=EfficientNetB0
--pretrained_model=output/EfficientNetB0_val/best_model_in_epoch_124/ppcls \

其中我的改动是，在resize的时候去掉了resize_short模式，将图片直接resize到288大小

有遇到的小伙伴帮忙答疑一下呀，谢谢~~

用MobileNetV3_large_x1_0训练分类模型，训练到第二个epoch，loss突然增大后又变为nan，这是为什么呢？大家有什么经验吗？

如题，开发者你好，请问一下目前这个库的动态图版本代码能正常运行么？和静态图版本的开发进度目前有哪些是不对齐的？

因为我想在HRNet下加上注意力机制，所以选择使用se+hrnet，在赢一个issue中反馈给我的是SE+HRNet需要有带SE的预训练，直接加载没有SE的预训练的模型精度会比较低。
我的问题：
1.是否有SE+HRNet的预训练
2.如果没有，我应该怎么训练能有一个较好的结果，是否有可行性的建议
3.是否有其他易于训练的注意力机制，相较于SE+HRNet在没有预训练模型的情况下容易训练。

你好，我使用自己的训练集（只有1类物体）进行train from scratch ,但是训练的过程中，top1和top2始终是1.0000（eval也是这样的），如图所示：
使用的配置文件为resnet50_vd.yaml,在配置文件中我改了类别数为2，请问这种情况应该怎末更改配置文件？还有一个问题是，如何拿PaddleClas训练完成的分类模型使用PaddleDetection进行目标检测？谢谢！

In operators.py
It seems that to_np, order and channel_first is not necessary
we already have a ToCHWImage function

I am training WRN-28-10 on CIFAR10 using PaddleClas. When batch size > 128, using larger batch size, training gets slower. A detailed comparison is shown below.

The time of the 2nd epoch is reported, so warm-up time is not counted. Experiments showed that the results were consistent.

This behavior is strange and unexpected. Could you help me to find the reason?

Code to reproduce is here.

Thank you very much!

貌似配置里面不能设置数据列表的delimiter，我这数据集里面文件名带空格，能用 | 的话会很方便

请教下大佬：
1、使用如下命令貌似只能推断一张图片，如果做到推断一个文件夹呢？类似paddle detection那样指定一个infer_dir。
python tools/infer/predict.py
-m model文件路径
-p params文件路径
-i 图片路径
--use_gpu=1
--use_tensorrt=True

2、windows环境下，怎样设置环境变量呢？我用aistudio上面的命令，Windows终端不认啊：
export PYTHONPATH=$PWD:$PYTHONPATH

你好，我想问一下，需要使用paddleClas从头训练自己的数据，但是那个train_list.txt 中除了图片路径外，位置坐标是使用中心点坐标和宽高，还是使用左上右下坐标呢？

你好，请问如果训练数据不均衡出现数据倾斜，目前PaddleClas是否有相对应解决办法，谢谢。

根据教程 导出模型的过程：
python tools/export_model.py
--model=MobileNetV3_large_x1_0
--pretrained_model=./output/MobileNetV3_large_x1_0/best_model_in_epoch_7/
--output_path=./convert/ \

报错如下：有经验的小伙伴帮忙看看？

你好，我用SSLD模型微调-基于ResNet50_vd_ssld预训练模型来做训练，然后生成了inference模型，想用PaddleHub进行部署的操作，有没有什么借壳快速部署的方式替换一下原来的module下的inference模型就可以启动部署的方式。

按照AI Studio中 30分钟玩转PaddleClas的教程，训练完模型并导出后，进行infer的时候报错：

这是指令：

请大神帮忙看看，谢谢！

模型调用命令，使用百度ResNet50_vd_10w的预训练模型：
set CUDA_VISIBLE_DEVICES=0
python -m paddle.distributed.launch --selected_gpus="0" tools/train.py -c ./configs/quick_start/ResNet50_vd_10w_finetune.yaml

FAQ中说“启动运行后，日志会实时输出到mylog/workerlog.*中，可以在这里查看实时的日志。”
但我为什么我运行后却找不到mylog文件夹？另外怎么可视化训练过程？

我的笔记本是window10 x64, 显卡是NVIDIA GeForce GTX 1650.

我按照示例程序编写训练语句，如下：python -m paddle.distributed.launch
--selected_gpus="0"
tools/train.py
-c ./configs/quick_start/ResNet50_vd.yaml

结果提示 ”gen_nccl_id ” has not been registered, 咨询QQ群说是window不支持多卡，请问针对我目前情况，应该如何写训练语句

在创建res2net 200层模型时，py2会报错：
UnicodeDecodeError: 'utf8' codec can't decode byte 0x80 in position 4: invalid start byte

因为层数超过26个英文字母，代码里的命名会出错
conv_name = "res" + str(block+2) + chr(97+i)

代码里的上一个分支应该增加res2net200
if layers in [101, 152, 200] and block == 2:

在windows10，cpu环境下运行下面的命令出现上面的错误
python -m paddle.distributed.launch tools/train.py -c ./configs/quick_start/ResNet50_vd.yaml

PaddleClas能否提供对cpu的支持呢？

尊敬的开发者，你好！
请问一下，飞桨有尝试使用HRNet来进行ImageNet的分类任务吗？

期待你的回复！

非常感谢这么棒的项目!!! 我对数据集的去重方式有点疑问, 因为我现在的数据集也需要去重, 但是我只知道使用sift找到特征点, 但是不同图片匹配到的特征点数量也是不同的, 那么怎么判断两幅图片的相似百分比呢? 然后设定阈值去去重图片

The concept: place confuse when someone tries to set available gpu places by indicating CUDA_VISIBLE_DEVICES

using Fleet interface, only the FLAGS_selected_gpus works

so we have to obtain gpu num by

gpu_num = paddle.fluid.core.get_cuda_device_count() if (
        'PADDLE_TRAINERS_NUM') and (
            'PADDLE_TRAINER_ID'
    ) not in env else int(env.get('PADDLE_TRAINERS_NUM', 0))

你好，我在v100上测试resnet50vd耗时接近24ms，你们的5ms以内是怎么测试的
