/usr/bin/anaconda3/envs/pytorch_1.7_gpu_new/bin/python: bad interpreter: No such file or directory

This error message indicates that the Python interpreter specified in the shebang line of a script is not found in the specified location. In this case, it seems that the interpreter at '/usr/bin/anaconda3/envs/pytorch_1.7_gpu_new/bin/python' does not exist or is not accessible.

To fix this issue, you can try the following steps:

1. Check that the Anaconda environment 'pytorch_1.7_gpu_new' is installed and activated. You can do this by running the command 'conda info --envs' and checking that the environment is listed.

2. Check that the Python interpreter is installed in the specified location. You can do this by navigating to the directory '/usr/bin/anaconda3/envs/pytorch_1.7_gpu_new/bin/' and checking that the file 'python' exists and is executable.

3. If the Python interpreter is not in the specified location, you can update the shebang line in the script to point to the correct location of the interpreter.

4. If the Python interpreter is in the correct location but still cannot be found, you may need to add the directory '/usr/bin/anaconda3/envs/pytorch_1.7_gpu_new/bin/' to your system's PATH environment variable. You can do this by adding the line 'export PATH="/usr/bin/anaconda3/envs/pytorch_1.7_gpu_new/bin/:$PATH"' to your shell configuration file (e.g. ~/.bashrc for bash).
