MXNetError: Check failed

[thapaliya123]

Hi, I have performed all the necessary steps as mentioned in the readme section. Also, for mxnet I have installed using the command "pip install mxnet-cu101". I have performed all these steps in Google Colab. Everything works fine, but when running command "sudo bash train.sh", I got the following error:

Please, guide me in this and how I can detach these errors and run TASN successfully
