This error is raised because the pickle version. It's abvious that the file path you read is encoded by byte mode by the prefix 'b'. You should convert it to string style.

isn't it because there is no "csv_mean_100/v_t_D9MYkEPEo.csv" ? You didn't share that file under the folder of "activitynet_feature_cuhk"....

[JJBOY]

These files are so big so you should download them by yourself as I writed in READEME.

the pth file( BMN_best.pth.tar) is big, but maybe the CSV file(v_t_D9MYkEPEo.csv) is not that big? Could u pls. share the CSV file? because your program running needs the csv file....

[JJBOY]

Please read the README carefully. I already offered the link to download the CSV files.

Okay, i see, in https://github.com/wzmsltw/BSN-boundary-sensitive-network

Download Datasets
We support experiments with publicly available dataset ActivityNet 1.3 for temporal action proposal generation now. To download this dataset, please use official ActivityNet downloader to download videos from the YouTube.

To extract visual feature, we adopt TSN model pretrained on the training set of ActivityNet, which is the challenge solution of CUHK&ETH&SIAT team in ActivityNet challenge 2016. Please refer this repo TSN-yjxiong to extract frames and optical flow and refer this repo anet2016-cuhk to find pretrained TSN model.

For convenience of training and testing, we rescale the feature length of all videos to same length 100, and we provide the rescaled feature at here Google Cloud or Baidu Yun. If you download features from BaiduYun, please use cat zip_csv_mean_100.z* > csv_mean_100.zip before unzip. After download and unzip, please put csv_mean_100 directory to ./data/activitynet_feature_cuhk/ .

the download link is: https://pan.baidu.com/s/19GI3_-uZbd_XynUO6g-8YQ#list/path=%2Fsharelink371590537-608856444000610%2Ftsn_feature&parentPath=%2Fsharelink371590537-608856444000610

meet the same issue when I donwload from Baidu, do you have any suggestion? thanks a lot

[lucky-23]

I met with the same issue. Can anyone please tell me how to solve this problem?
