convert_elapsed_time
(seconds)[source]¶ Convert elapsed time in seconds to HH:MM:SS format
-
ml4chem.utils.
dynamic_import
(name, package, alt_name=None)[source]¶ A dynamic module importer
- Parameters
name (str) – Name of the module to be imported.
package (str) – Path to package. Example: ml4chem.atomistic.features
alt_name (str) – Alternative module_name.
- Returns
_class – An class object.
- Return type
obj
-
ml4chem.utils.
get_chunks
(sequence, chunk_size, svm=True)[source]¶ A function that yields a list in chunks
- Parameters
sequence (list or dictionary) – A list or a dictionary to be split.
chunk_size (int) – Number of elements in each group.
svm (bool) – Whether or not these chunks are going to be used for kernel methods.
-
ml4chem.utils.
get_hash
(image)[source]¶ Get the SHA1 hash of an image object
- Parameters
image (object) – An image to be hashed.
- Returns
_hash – Hash of image in string format
- Return type
str
-
ml4chem.utils.
get_neighborlist
(image, cutoff)[source]¶ Get the list of neighbors
- Parameters
image (object) – ASE image.
- Returns
- Return type
A list of neighbors with offset distances.
-
ml4chem.utils.
get_number_of_parameters
(model)[source]¶ Get the number of parameters
- Parameters
model (obj) – Pytorch model to perform forward() and get gradients.
- Returns
(total_params, train_params) tuple with total number of parameters and
number of trainable parameters.
-
ml4chem.utils.
lod_to_list
(data, svm=False, requires_grad=False)[source]¶ List Of Dict (lod) to list
- Parameters
data (list) – A list with ml4chem dictionaries. Those ones coming from get_chunks()
svm (bool, optional.) – Whether or not these chunks are going to be used for kernel methods, by default False.
requires_grad (bool, optional.) – Do we require gradients?, by default False.
- Returns
A list of tensors or list of float.
- Return type
_list
-
ml4chem.utils.
logger
(filename=None, level=None, format=None, filemode='a')[source]¶ A wrapper to the logging python module
This module is useful for cases where we need to log in a for loop different files. It also will allow more flexibility later on how the logging format could evolve.
- Parameters
filename (str, optional) – Name of logfile. If no filename is provided, we output to stdout.
level (str, optional) – Level of logging messages, by default ‘info’. Supported are: ‘info’ and ‘debug’.
format (str, optional) – Format of logging messages, by default ‘%(message)s’.
filemode (str, optional) – If filename is specified, open the file in this mode. Defaults to “a”. Supported modes are: “r” (read), “w” (write), “a” (append).
- Returns
A logger object.
- Return type
logger
