Could find no file with path

[heraldob]

when i run:

!python generate.py --model tecogan_model.h5 --input-dir-lr frames/input_video/ --output-dir results/user
!ffmpeg -i results/user/output_frame_%04d.png -r 24/1 -y user_video_hr.mp4

I get the following error:

I think you use google colab.

ImportError: libcudart.so.10.0: cannot open shared object file: No such file or directory

It said there is no cuda10.0 environment, this runtime seems to unsupport cuda10.0.
So, could you please change to use nnabla-ext-cuda114 not nnabla-ext-cuda100 as follows?

!pip install nnabla-ext-cuda114
!pip install ffmpeg
!git clone https://github.com/sony/nnabla-examples.git
%cd nnabla-examples/video-superresolution/tecogan
