# Troubleshooting common errors Here, I've collected the output messages of some of the common errors I run into while using the code. I've included the solutions where I've found them, along with more details about what caused the error. If you encounter an error, try searching for parts of the error message in this document to see if it here. ## Contents - [Cannot connect to host in VSCodium](#cannot_connect_to_host_in_vscodium) - [Is the virtual environment activated?](#is_the_virtual_environment_activated) - [Order of the imports matters on Trillium](#order_of_the_imports_matters_on_trillium) - [Directory not empty](#directory_not_empty) - [Errors running tests from VSCodium](#errors_running_tests_from_vscodium) - [NaN values](#nan_values) - [Matplotlib has no attribute `__version_info__`](#matplotlib_has_no_attribute___version_info__) - [Disk quota exceeded](#disk_quota_exceeded) - [Importing packages in the wrong order on Trillium](#importing_packages_in_the_wrong_order_on_trillium) - [Cannot `make clean html` docs](#cannot_make_clean_html_docs) - [Do you have more than one day in the data?](#do_you_have_more_than_one_day_in_the_data) - [Some variables aren't defined all the way to the end of 2020](#some_variables_arent_defined_all_the_way_to_the_end_of_2020) - [Unable to install `tensorflow` locally](#unable_to_install_tensorflow_locally) --- [back to top](#top) ## Cannot connect to host in VSCodium Sometimes the VSCodium server on a remove machine will get corrupted, causing you to be unable to connect to the remote via VSCodium, but you will still be able to log in via terminal just fine. This can happen when logging out without saving a file or if you lose internet connection suddenly and don't restore it within a few minutes. I highly recommend closing the remote connection in VSCodium every time you are done working on the remote. To fix the corrupted server, log into the remote via terminal and find the `.vscodium-server/` directory. It is usually in your home directory. Rename that directory. ```console username@:~/$ mv .vscodium-server/ .vscodium-server_old/ ``` This will keep the contents of your old setup, just in case. However, since now there is no `.vscodium-server/` directory, when you now log in to the remote via VSCodium, it will reconstruct a new server directory, which should solve the issue with connecting. If that works, you can then delete the old server directory and it's contents. ```console username@:~/$ rm -rf .vscodium-server_old/ ``` Be sure to reinstall all your extensions on this new version of the remote VSCodium server. --- [back to top](#top) ## Is the virtual environment activated? When trying to regenerate the documentation `html` files, you may encounter this error: ```console username@animus-c:~/$ make clean html /home//miniconda3/bin/python: No module named sphinx make: *** [Makefile:19: clean] Error 1 ``` To fix this, activate the `conda` environment. --- [back to top](#top) ## Order of the imports matters on Trillium The error: ```console 2025-10-20 15:32:03.597518: I tensorflow/core/util/port.cc:153] oneDNN custom operations are on. You may see slightly different numerical results due to floating-point round-off errors from different computation orders. To turn them off, set the environment variable `TF_ENABLE_ONEDNN_OPTS=0`. 2025-10-20 15:32:03.611818: E external/local_xla/xla/stream_executor/cuda/cuda_fft.cc:485] Unable to register cuFFT factory: Attempting to register factory for plugin cuFFT when one has already been registered 2025-10-20 15:32:03.625403: E external/local_xla/xla/stream_executor/cuda/cuda_dnn.cc:8454] Unable to register cuDNN factory: Attempting to register factory for plugin cuDNN when one has already been registered 2025-10-20 15:32:03.629447: E external/local_xla/xla/stream_executor/cuda/cuda_blas.cc:1452] Unable to register cuBLAS factory: Attempting to register factory for plugin cuBLAS when one has already been registered 2025-10-20 15:32:03.641665: I tensorflow/core/platform/cpu_feature_guard.cc:210] This TensorFlow binary is optimized to use available CPU instructions in performance-critical operations. To enable the following instructions: AVX2 AVX512F AVX512_VNNI AVX512_BF16 FMA, in other operations, rebuild TensorFlow with the appropriate compiler flags. ``` This happens when you try to import `tensorflow` or `keras` before using `xarray` to load the data that will be used by the model. --- [back to top](#top) ## Directory not empty The error: ```console OSError: [Errno 39] Directory not empty: 'inputfiles/no2_2019_JFM/' ``` This happens when I try to overwrite a directory or data file where any file to be overwritten is loaded into a data structure in an active Jupyter notebook cell. This most often happens when I'm testing out functions which write input files or metadata files and I've loaded that file in another cell to test whether it works. The solution to this is to restart the kernel in that notebook. Example: executing these two cells in a row: ```python from unox.HPC.data0.dataset import uarray input_u_arr = uarray('no2_2019_JFM', is_input_set=True) input_u_arr.xr ``` ```python from unox.input import copy_input_files this_output = copy_input_files( source_input_set = 'no2_2019', output_dir = 'no2_2019_JFM', keep_vars = 'all', # keep_vars = ['no2'], start_date = '2019-01-01', end_date = '2019-03-31', overwrite=True, ) this_output.xr ``` --- [back to top](#top) ## Errors running tests from VSCodium Error when running a test using the GUI in VSCodium, clicking on the "run" button next to the test definition: ```console Test result not found for: ./tests/test_input.py::test_make_input_metadata_file ``` After running `pytest --collect-only`, I got the output ```console E ValueError: conflicting sizes for dimension 'time': length 192 on 'time' and length 30 on {'time': 'no2', 'lat': 'no2', 'lon': 'no2'} ``` which told me that I'd incorrectly set the length of the time dimension on a new example dataset. --- [back to top](#top) ## `NaN` values If encountering `NaN` values, take a look at the time interval over which data is being used. For the `nox` variable, all values past 2020-04-24 are `NaN`, therefore, correlation plots between `nox` (or `truth`) over intervals which include dates past 2020-04-24 will produce the error: ```console ValueError: autodetected range of [nan, nan] is not finite ``` --- [back to top](#top) ## Matplotlib has no attribute `__version_info__` Here is the error I was encountering: ```console --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) Cell In[5], line 1 ----> 1 from unox.plotting import plot_extent 3 extent_plot = plot_extent(sample_dataset) File ~/checkouts/readthedocs.org/user_builds/unox/checkouts/latest/src/unox/plotting.py:1 ----> 1 import matplotlib.pyplot as plt 2 import matplotlib as mpl 3 import numpy as np File ~/checkouts/readthedocs.org/user_builds/unox/envs/latest/lib/python3.9/site-packages/matplotlib/pyplot.py:2500 2498 dict.__setitem__(rcParams, "backend", rcsetup._auto_backend_sentinel) 2499 # Set up the backend. -> 2500 switch_backend(rcParams["backend"]) 2502 # Just to be safe.

It was also occurring when someone else was trying to run a function which imported `matplotlib.pyplot` in a Jupyter notebook. They were able to import just `matplotlib` without error. That notebook was running fine on my Animus environment and it was also running fine when that other person imported `matplotlib` in the Python interpreter using the same environment. ```console @animus-c:unox$ conda activate uplt (uplt) @animus-c:unox$ python Python 3.9.25 (main, Nov 3 2025, 22:33:05) [GCC 11.2.0] :: Anaconda, Inc. on linux Type "help", "copyright", "credits" or "license" for more information. >>> import matplotlib.pyplot >>> ``` Looking through the error message, I saw that the error was occurring in the `backend_inline.py` script in the `matplotlib-inline` package. That explains why it was only occurring when running in a Jupyter notebook and not in the interpreter. The reason it was running fine on my environment and not in Read the Docs or the other person's notebooks is that we had [different versions of `matplotlib-inline`](https://github.com/ipython/matplotlib-inline/tags). My environment was using `v0.1.7`, which was released on 2024-04-15. The other environments were using `v0.2.1`, which was released on 2025-10-23. I created my environment between those two dates, so it installed `v0.1.7`, the most up-to-date release at the time. I made a post about this on the `matplotlib-inline` GitHub, [GitHub - Matplotlib-Inline Issue #60: AttributeError: module 'matplotlib' has no attribute '__version_info__'](https://github.com/ipython/matplotlib-inline/issues/60). I encountered this error in the Analysis Notebook when it gets pushed to the Read the Docs site. I don't see the error when running the notebook on Animus. It happens the first time `matplotlib` is imported. Harshil also encountered the same error when he tried creating the input files as the `input` module imported `matplotlib.pyplot`. I've since removed the import of `matplotlib` from the `input` module because it is not needed, but it is still an issue. --- [back to top](#top) ## Disk quota exceeded ```console [username@trig-login01 unox]$ git pull error: cannot open '.git/FETCH_HEAD': Disk quota exceeded ``` Fix: Delete some data to free up room. I deleted a bunch of old stuff from `HPC_runs/`.

Basically, I need to load `xarray` and use it to import from a file before I load the `keras` / `tensorflow` modules. On 2026-02-09, I hit this particular error which was caused by me trying to import functions from keras before loading the xarray package: ```console Traceback (most recent call last): File "/scratch//Postdoc/unox/src/unox/HPC/run_model.py", line 61, in uarr = uarray(inputfiles, is_input_set=True) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/scratch//Postdoc/unox/src/unox/HPC/data0/dataset.py", line 50, in __init__ self.xr = get_dataset( ^^^^^^^^^^^^ File "/scratch//Postdoc/unox/src/unox/HPC/data0/dataset.py", line 150, in get_dataset xr_dataset = load_dataset(file_path, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/scratch//Postdoc/unox/src/unox/HPC/data0/dataset.py", line 188, in load_dataset xr_dataset = xr.open_dataset(file_path) ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home//.virtualenvs/unoxTrilliumNC/lib/python3.12/site-packages/xarray/backends/api.py", line 573, in open_dataset backend_ds = backend.open_dataset( ^^^^^^^^^^^^^^^^^^^^^ File "/home//.virtualenvs/unoxTrilliumNC/lib/python3.12/site-packages/xarray/backends/netCDF4_.py", line 646, in open_dataset store = NetCDF4DataStore.open( ^^^^^^^^^^^^^^^^^^^^^^ File "/home//.virtualenvs/unoxTrilliumNC/lib/python3.12/site-packages/xarray/backends/netCDF4_.py", line 376, in open import netCDF4 File "/home//.virtualenvs/unoxTrilliumNC/lib/python3.12/site-packages/netCDF4/__init__.py", line 3, in from ._netCDF4 import * ImportError: /cvmfs/soft.computecanada.ca/easybuild/software/2023/x86-64-v3/MPI/gcc12/openmpi4/netcdf-mpi/4.9.2/lib64/libnetcdf.so.19: undefined symbol: H5Pset_coll_metadata_write ``` I remember running into this sometime in 2025. I want to look back through my logs to see if I can find if that was the same error message that earlier time. --- [back to top](#top) ## Cannot `make clean html` docs ```console (uplt) username@animus-c:~/unox/docs$ make clean html Removing everything under '_build'...
