Unhashable type list

The error message "TypeError: unhashable type list type: 'list' " typically indicates an attempt to employ a list as a hashable argument. Hashing an unhashable object leads to an error. For example, using a list as a dictionary key is infeasible since lists aren't hashable.

Explore your training options in 10 minutes Get Started. Python dictionaries only accept hashable data types as a key in a dictionary. A list is not a hashable data type. In this guide, we talk about what this error means and why you see it in your code. Dictionaries have two parts: keys and values. Keys are the labels associated with a particular value. While values can be of any data type, from lists to strings , only hashable objects are acceptable as keys.

I am Dosu , a bot designed to assist you with your technical issues, answer your questions, and guide you towards becoming a contributor. While you're waiting for a human maintainer, I'm here to help you with your issue. Let's get started! Based on the error message you provided, it seems like the issue is related to the metadata being passed to the Qdrant. The error "TypeError: unhashable type: 'list'" is typically raised when you're trying to use a list as a dictionary key or as an element in a set, both of which require their elements to be hashable immutable.

The easiest way to fix the TypeError: unhashable type: 'list' is to unhashable type list a hashable tuple instead of a non-hashable list as a dictionary key. They usually contain a heterogeneous sequence of elements that are accessed via unpacking or indexing.

This error occurs when you try to use a list as key in the dictionary or set. As you know 'list' is an unhashable object that can not be used as a key for any dictionary or set. In simple terms, this error occurs when you try to hash a 'list' , which is an unhashable object. To fix this error, you can convert the 'list' into a hashable object like 'tuple' and then use it as a key for a dictionary as shown below. To fix this error, you can convert the 'list' into a hashable object like tuple then use it as a key for 'set' as shown below:. In python, hashing is the method of encoding the data into a fixed-size integer which represent the original value.

The Python TypeError: unhashable type: 'list' usually means that a list is being used as a hash argument. This error occurs when trying to hash a list, which is an unhashable object. For example, using a list as a key in a Python dictionary will cause this error since dictionaries only accept hashable data types as a key. The standard way to solve this issue is to cast a list to a tuple, which is a hashable data type. Install the Python SDK to identify and fix these undefined errors.

Unhashable type list

For example, using a list as a key in a Python dictionary will throw the TypeError because you can only use hashable data types as a key. This tutorial will go through the error in detail and how to solve it with the help of code examples. TypeError occurs whenever you try to perform an illegal operation for a specific data type object. In the example, the illegal operation is hashing, and the data type is List. By definition, a dictionary key needs to be hashable. An object is hashable if it has a hash value that remains the same during its lifetime. A hash value is an integer Python uses to compare dictionary keys while looking at a dictionary.

This characteristic finds significance primarily in the context of dictionary keys. The TypeError: unhashable type: 'list' error typically occurs when a mutable data type, like a list, is used as a key in a dictionary or as an element in a set, which require their elements or keys to be hashable immutable. To resolve this issue, you would need to ensure that you're not using a list in a context where a hashable type is required. In each iteration of the for loop, we calculate the average of all the grades a student has earned. You can hash only those objects which are hashable or objects that can't be altered. This method is a user-friendly interface that creates embeddings for each text, initializes the Qdrant database as an in-memory docstore by default overridable to a remote docstore , and adds the text embeddings to the Qdrant database. They usually contain a heterogeneous sequence of elements that are accessed via unpacking or indexing. Updated docs with new functions examples. Hashing such objects always produces the same result, so they can be used as the keys for dictionaries. New issue. Error: TypeError unhashable type 'list' This error occurs when you try to use a list as key in the dictionary or set. Based on the code you've provided and the error message you're encountering, it seems like the issue might be related to the way the Qdrant. What are metaclasses in Python?

Dictionaries have two parts: keys and values. For example, using a list as a key in a Python dictionary will cause this error since dictionaries only accept hashable data types as a key. While values can be of any data type, from lists to strings , only hashable objects are acceptable as keys. With this capability also comes potential risks. Recommended Posts:. It will allow Python to create unique hash values for the keys. It extends support to passing multiple named arguments into the factory if the factory takes more than a single argument. The Python TypeError: Unhashable Type: 'List' can be fixed by casting a list to a tuple before using it as a key in a dictionary:. I included a unit-test that shows an issue that was caused in LangServe in the RemoteClient. To resolve this issue, you would need to ensure that you're not using a list in a context where a hashable type is required. This list will contain dictionary records of each student and their grades. Rohit Yadav - Mar 9. James Gallagher is a self-taught programmer and the technical content manager at Career Karma.
