As we work toward Idyl E3 2.6.0 we keep the Release Notes page updated with what’s new, tweaked, and fixed in 2.6.0. Probably the most significant new feature is support for GPUs.
Less exciting but still useful is how models that fail to load are handled in 2.6.0. Previously when a model failed to load it would be retried the next time the model is needed. If nothing has changed that could help the model load then this can result in needlessly trying to load the model and failing. In 2.6.0 if a model fails to load it is added to a blacklist and Idyl E3 will not attempt to reload any model on the blacklist until Idyl E3 is restarted. A message will be included in Idyl E3’s log when a model is blacklisted.
A model can fail to load for a few reasons. The most common reasons are:
- The model file defined in the manifest does not exist or cannot be read due to insufficient permissions.
- The model’s encryption key is invalid.
- The model’s license key is invalid.
IDYL_E3_HOME Environment Variable
Also noteworthy is the IDYL_E3_HOME environment variable that must be set. If you launch Idyl E3 through the AWS Marketplace it is taken care for you. If not, you just need to set IDYL_E3_HOME to the location where you extracted Idyl E3 (we recommend /opt/idyl-e3):
Most of Idyl E3’s scripts reference the IDYL_E3_HOME environment variable to know where to find its file.
The last new thing we’ll mention here is the new tool included with Idyl E3 called the Model Downloader. When run, this command line tool shows you models available for download from us that you can download and install into your Idyl E3. No more downloading via your web browser and then having to copy to Idyl E3. You can now download models straight from Idyl E3. The tool will prompt you for a login (it is your Mountain Fog account username and password – register for free if you need a login) and then present you with a simple menu. The tool also supports a non-interactive mode so you can script the download of models!
We’ll give a more detailed look at the Model Downloader tool once 2.6.0 is released so stay tuned.
