Ref: fastai-v2 Normalize Class class Normalize(DisplayedTransform): Your suggestions / ideas are highly appreciated. If anyone is familiar with or having the same issue, please let me know.
Once I use my own Normalize2 class as shown below (keeping mean, std in the memory and moving them to GPU every time encodes is called - highly inefficient), it works.
#Finetunes meaning windows
This problem should have something to do with CUDA and accessing GPU tensors (mean, std) with multiple windows processes, according to my initial study.
This is because initially, mean and std are moved to GPU when om_stats(…) is called, and by the time batches are formed from multiple processes and follow Normalize.encodes(…), the mean and std are taken as 0 in GPU. While feeding the batches from multiple processes (num_workers=1 or > 1), the batches are found to contain nan due to the division mean and std being 0 (ref Normalize.encodes) Resnet34 (pre-trained) model uses pre-trained weights hence vision_learner calls om_stats(…) with pre-trained resnet relevant mean, and std which will be moved to GPU (if cuda is available) Platform: Windows 10圆4, GPU: Nvidia 1080Ti Learn = vision_learner(dls, resnet34, metrics=error_rate) # normalize=True by default t_start_method('spawn') # default for windows Path = untar_data_ex(url, base=Path(ction('DATA_PATHS').FASTAI_DATA))ĭls = om_name_func(path, files, label_func, item_tfms=Resize(224), num_workers=1) # verbose=True
Last summer, a number of community participants registered dismay at renderings, in particular design plans for the corner of 23rd and Union, which was criticized for not highlighting the corner as a “sacred space.Please refer to the program below: from import *įrom import untar_data_exįrom import EnvConfig While the MOU has resulted in a number of wins for the community such as designating 30% of the housing units as affordable, promising best efforts are made on the part of Lake Union Partners to ensure commercial space is designed and operated to prioritize affordability for small African American owned businesses, and coordinating with Africatown to “maximize the participation of Black owned consultants, contractors, and other workers.” One of the most striking impacts of Africatown on Midtown Square project can be observed in how the project design has changed over time to adapt to community feedback. The MOU is a non-binding document that “details the goals for maximizing the contributions of the Central Area African-American community to the project.” In 2017, Lake Union Partners entered into a Memorandum of Understanding (MOU) with Africatown Community Land Trust and Forterra. In addition to acquiring the land at the south end of the site to retain for permanent community ownership, Africatown Community Land Trust has also urged Lake Union Partners to be accountable for how its developments impact the surrounding neighborhood and African American community. Lake Union Partners’ developments have radically changed the corner of 23rd and Union in recent years. The Central, another Lake Union Partner’s Project is located directly east of the future Midtown Square, while the Stencil, which can be seen in the far left of the photograph, is directly west of the site. An international design competition is slated to open this September.
#Finetunes meaning full
Urban designer Renee Kemp-Rotan described how the discovery of the Clotilda, the last ship that transported enslaved Africans to North America, has catalyzed efforts to construct an Africatown living monument over four sites, including a full scale replica of the Clotilda, a convention center, pavilion, environmental jobs center, African Museum, permanently affordable housing, and more.
The 2019 Design Weekend was also a more reflective event which participants learned about transformative plans for original Africatown in Mobile, Alabama. The 2019 Imagine Africatown Design Weekend was a quieter affair that took place in Washington Hall, a little over a mile away from where bulldozers have begun to rip through the 23rd and Union site in preparation for construction of Lake Union Partners’ Midtown Square project (formerly called the Midtown Commons).
