when trying to launch an instance like in the tutorial with
$ fe2 launch base ami-08d658f84a6d84a80 50 m5.xlarge

I get this error:

Traceback (most recent call last):
File "/anaconda3/bin/fe2", line 10, in

assert self._describe('key_pairs', {'key-name':keyname}), 'default key not found'
AssertionError: default key not found

What could be the cause? The was credentials should be ok as $ was s3 ls does not yield an error.

I am using anaconda, python 3.6.7 pretty much standard setup.

I ran into the same issue. Here are the details of my experience:

Create env to test fastec2:

$ conda create -y -n fastec2env python

Executing this on 2019-02-22T0939 installs the following:

Then I activate the env:

$ conda activate fastec2env

Then I install fastec2 within the activated env:

$ python -m pip install git+https://github.com/fastai/fastec2.git

Trying to launch an instance produces an error:

Could this be an AWS configuration issue? This command works, which seems to confirm that that aws is correctly configured, since I can create an instance with that AMI manually:

$ aws ec2 run-instances --image-id ami-005bdb005fb00e791 --instance-type m5.xlarge --security-groups default

Sorry, my mistake. I did not have a defined key-pair with the name "default". When I fix that, and manually specify the key pair, the security group, then I get a different error when I try to launch an instance. I will experiment with this more. Sorry for sowing confusion.

FWIW, the error I get now is just a timeout:

really installing/creating a key pair called default was the "key" here, not AIM but in "network and security" -> key pairs

qbatten commented

I am getting this error as well right now and having trouble following what your solution was. I have a key-pair in EC2 called 'default', in ~/.ssh/default.pem, but I cant seem to get it to recognize the key. I've tried the following commands but get that same error every time. Any one able to help out with this?

fe2 launch --name base4 --ami ami-005bdb005fb00e791 --disksize 50 --instancetype m5.xlarge --keyname default --secgroupname default

fe2 launch --name base4 --ami ami-005bdb005fb00e791 --disksize 50 --instancetype m5.xlarge --keyfile ~/.ssh/default.pem
