Error EnvironmentNameNotFound: Could not find conda environment: test_dpctl You can list all discoverable environments with conda info --envs. occurs still in the test phase, but the environment still activates and runs the tests, so I will consider this an unrelated bug (the error is raised when conda create is called)
