Course Introduction:The reason for the error "NoSuchDimensionError(name)" in python is usually caused by using a non-existent dimension name. This may be caused by using the wrong dimension name in the program or by the dimension being missing from the data structure. For example, this error may occur if the program attempts to access a dimension of a multidimensional array that does not exist. How to solve To solve this error, you should first check whether the dimension names used in the program are correct. If the dimension name is wrong, it should be corrected to the correct name. If the dimension name is correct, then the data structure should be checked to see if the dimension is missing. If so, the dimension should be added or the data structure should be replaced.
