There's a discussion of the issue at

    https://stackoverflow.com/questions/39660934/error-when-using-importlib-util-to-check-for-library/39661116

To remove the error,

-    $PYTHON_TEST -c "import imp; imp.find_module('pysam')"
-    $PYTHON_TEST -c "import imp; imp.find_module('numpy')"
+    $PYTHON_TEST -c "from importlib import util; util.find_spec('pysam')"
+    $PYTHON_TEST -c "from importlib import util; util.find_spec('numpy')"

To print an error message, perhaps the awkward-looking

-    $PYTHON_TEST -c "import imp; imp.find_module('pysam')"
-    $PYTHON_TEST -c "import imp; imp.find_module('numpy')"
+    $PYTHON_TEST -c "from importlib import util; print('pysam not found') if util.find_spec('pysam') is None else None"
+    $PYTHON_TEST -c "from importlib import util; print('numpy not found') if util.find_spec('numpy') is None else None"
