upload_file error: No such file or directory

[Meng Wang]

I’m working on the Upload and Execute in Jupyter Lab. I am able to create a slice and a node. But when I’m trying to upload a local file to the node, I receive an error message saying

Exception: [Errno 2] No such file or directory: ‘/Users/wangmeng/Documents/some_folder_names/myScript.sh’

And here’s the code I wrote

try:
node = slice.get_node(name=”Node1″)

result = node.upload_file(‘/Users/wangmeng/Documents/some_folder_names/myScript.sh’, ‘myScript.sh’)
except Exception as e:
print(f”Exception: {e}”)

I have read an earlier post in the forum and learned that the first argument for upload_file should be the local path of the file, while the second argument is the path to the remote node. I’m not sure if I have formatted it correctly.

The script file that I’m trying to upload is read&write accessible to everyone.

That looks correct.

Are you able to open and read the file directly in the code?

It looks like you are running this on a Mac.  Are you running it in a virtual environment on the Mac?  In some cases a virtual environment will not be able to access files outside of the virtual environment.

Try opening and reading the file directly.

Thank you Paul for pointing that out. I realize that I had a misunderstanding about the concept of local. I thought it means my local drive, but what it actually means is the virtual environment. I am able to upload the file after uploading the file from my local drive to the VM. Thanks for the help!
