[BUG]: IProgress not found. Please update jupyter & ipywidgets

#359 Summary of the bug I am running the tutorials found here - Mapping vehicles & Tiling tutorial

And the code is breaking whenever the tqdm module is called (to show the status bar)!

Steps to reproduce the bug

I am running the mapping cars tutorial & the Tiling tutorial. (Links given above) For the car mapping tutorial the code breaks here -

The error occurs on the following line: trainer = sol.nets.train.Trainer(config)

For the Tiling tutorial the code breaks here -

raster_bounds_crs = raster_tiler.tile('/path/to/raster/file/3band/PS-RGB_mosaic_013022223133.tif')

Buggy behavior and/or error message

The error log had the following: Exception ignored in: <function tqdm.__del__ at 0x7fe617c33290> Traceback (most recent call last): File "/opt/conda/envs/solaris/lib/python3.7/site-packages/tqdm/std.py", line 1087, in __del__ self.close() File "/opt/conda/envs/solaris/lib/python3.7/site-packages/tqdm/notebook.py", line 247, in close self.sp(bar_style='success') AttributeError: 'tqdm_notebook' object has no attribute 'sp'

followed by -

ImportError: IProgress not found. Please update jupyter and ipywidgets.......

Expected behavior

Model should be downloaded, without any issues.

Environment information

• OS: GNU-Linux, GCP Deep Learning Platform with TF2.1 pre-installed
• solaris version: 0.3.0
• python version: 3.7.6
• tqdm: 4.48.0 I am using Jupyterlab on a GCP VM

Additional context

Hardware: N1 4vCPUs, 15GB RAM (GCP) NVidia Tesla T4

I get the above error while running the following notebook https://github.com/jshermeyer/solaris_cowc/blob/master/map_vehicles_cowc.ipynb

I first got the error while downloading the VGG16 pre-trained weights. So I downloaded the model and then copied it to the required directory. And then again ran the training code. However then I got the error while it was downloading the SpaceNet model weights.

While downloading the weights the error occurs for the status bar. from the get_model >> download_model module.

The same error re-occurred when I was running the Tiling tutorial

Again while running the tqdm module.

I have tried the steps as given in the following SF answer

• re-installing ipywidgets
• and enabling widget extensions

i meet same the error on my juptyer notebook (using docker). i resolve it by changing the notebook dir. if you run jupyter notebook using root dir, using the --notebook-dir to change the dir may help you.

Sir, my dir is the Desktop. But I meet the same error.

I solved this by chaging

from tqdm.notebook import tqdm as tqdm

to

from tqdm import tqdm

solved this
