We use YAML files to specify our conda and pip environments. In them we can specify which version numbers we need using, for example, any one of these lines
- cudatoolkit=10.2.89
- cudatoolkit=10.2.*
- cudatoolkit==10.2.89
- cudatoolkit==10.2.*
I am having trouble finding the documentation for what == vs. = means in these package requirements and what other restrictions could be written and how.
What is the difference in this setting between = and ==? Do these meanings differ between conda and pip? Where is the correct documentation (Google & Bing are not great at searching for symbols like those)?
