Thank you for your sharing of 3DCNN, its terse and beautiful. However, got this error when i tried to run the UCF101 database directly. BTW, the plot in keras is now: from keras.utils.vis_utils import plot_model.

Could you tell me the environment? (version of python, opencv) If you haven't installed pydot, plese install it.(pip install pydot) OpenCV Error can occur when you didn't build OpenCV with ffmpeg. At last, you might have used old version of 3dcnn.py. I've already updated it and I import plot_model from keras.utils.vis_utils in the latest code.

Hi, I think I found the problem. My environment is python2.7 and opencv3. I think the problem is just about the format of dataset. When I downloaded the UCF101 database, the videos are under those sub folders with folder name as label, but when you load the videos, you load directly the videos and extract the label from the name of the videos, which, in my case, loaded the folders. Maybe you could add this part about the data format in the intro, thank you.

1%| | 1/101 [00:00<00:04, 22.50it/s] 我也遇见了和一楼一样的问题，是读文件时出问题了。在UCF101/PushUps/文件夹下还需要再次遍历读取视频。

@Linranran 请问代码怎么改呀？我也遇到了同样的问题

[Linranran]

@bingo9062 这个问题是解压文件时候产生的问题，你要是直接用 tar -xzvf 解压数据集文件试试。我是直接右击解压的，就出现问题了。解决方法大概就是：再遍历子文件夹，读取图片。label的赋值也要稍微变一下，你自己多试试。

我发现都放到一个文件夹下就好了，我是mac系统，不知为什么opencv处理avi文件报错，mp4文件没问题

Hi, Can you please share how you solved this issue as I am facing a similar issue
