Importerror Dll Load Failed The Specified Path Is Invalid

This is not what is happening to you, but I include it because it is another common class of problems you have when importing a compiled library. You may get an error message which indicates that the library load failed for another reason, like:

Find the loader for a module, optionally within the specified path. If themodule is in sys.modules, then sys.modules[name].__loader__ isreturned (unless the loader would be None or is not set, in which caseValueError is raised). Otherwise a search using sys.meta_pathis done. None is returned if no loader is found.

A dotted name does not have its parents implicitly imported as that requiresloading them and that may not be desired. To properly import a submodule youwill need to import all parent packages of the submodule and use the correctargument to path.

An abstract method for finding a loader for the specifiedmodule. Originally specified in PEP 302, this method was meantfor use in sys.meta_path and in the path-based import subsystem.

An abstract method for finding a spec forthe specified module. If this is a top-level import, path willbe None. Otherwise, this is a search for a subpackage ormodule and path will be the value of __path__ from theparent package. If a spec cannot be found, None is returned.When passed in, target is a module object that the finder mayuse to make a more educated guess about what spec to return.importlib.util.spec_from_loader() may be useful for implementingconcrete MetaPathFinders.

A legacy method for finding a loader for the specifiedmodule. If this is a top-level import, path will be None.Otherwise, this is a search for a subpackage or module and pathwill be the value of __path__ from the parentpackage. If a loader cannot be found, None is returned.

An abstract method for finding a spec forthe specified module. The finder will search for the module onlywithin the path entry to which it is assigned. If a speccannot be found, None is returned. When passed in, targetis a module object that the finder may use to make a more educatedguess about what spec to return. importlib.util.spec_from_loader()may be useful for implementing concrete PathEntryFinders.

A legacy method for finding a loader for the specifiedmodule. Returns a 2-tuple of (loader, portion) where portionis a sequence of file system locations contributing to part of a namespacepackage. The loader may be None while specifying portion tosignify the contribution of the file system locations to a namespacepackage. An empty list can be used for portion to signify the loaderis not part of a namespace package. If loader is None andportion is the empty list then no loader or location for a namespacepackage were found (i.e. failure to find anything for the module).

An abstract method to return the source of a module. It is returned asa text string using universal newlines, translating allrecognized line separators into '\n' characters. Returns Noneif no source is available (e.g. a built-in module). RaisesImportError if the loader cannot find the module specified.
