Hi,
I have a problem running the cosco on physical environment. I run it on VLAN mode. I don't have access to azure, AWS or any other famous cloud provider. I have access to 10 VMs with same resources you have been used in Demo video. I have not ran any specific command on my worker VMs, except for copying the public key.
According to your last video on the youtube playlist, we should run some kind of deplyoyment on the VMs, but I couldn't figure out how can I do that with out using the AZ command you used in the video, and I think my error that I have pasted as the subject of this issue happens because of that.
Could any one please help me with how can I deploy worker's applications on my vms without using cloud provider's specific packages?

to expand my question further, This is the error I face when I run the main.py file

Traceback (most recent call last):

The error occurs when running this line of code
outputHostsData = Parallel(n_jobs=num_cores)(delayed(self.parallelizedFunc)(i) for i in self. Hosts)
