fix possible pandas import error during tensorboard tests (#29650)
Summary:
TensorBoard tests using SummaryWriter() may fail with a pandas import
complaint if TensorFlow packages are installed in the same python
environment as PyTorch:
Traceback (most recent call last):
File "test_tensorboard.py", line 212, in test_writer
with self.createSummaryWriter() as writer:
File "test_tensorboard.py", line 64, in createSummaryWriter
return SummaryWriter(temp_dir)
...
File "[...]/site-packages/pandas/core/arrays/categorical.py", line 52, in <module>
import pandas.core.algorithms as algorithms
AttributeError: module 'pandas' has no attribute 'core'
The exact failure may depend on the pandas version. We've also seen:
File "[...]/site-packages/pandas/core/arrays/categorical.py", line 9, in <module>
import pandas.compat as compat
AttributeError: module 'pandas' has no attribute 'compat'
The module import chain leading to the failure is tensorboard imports
tensorflow imports tensorflow_estimator imports pandas. pandas includes
a submodule named 'bottleneck', whose name collides with the PyTorch
'test/bottleneck/' subdirectory.
So IF tensorboard, tensorflow, tensorflow_estimator, and pandas are
installed in the python environment AND IF testing is run from within
PyTorch's 'test/' directory (or maybe just with 'test/' in PYTHONPATH,
etc.), then TensorBoard tests using SummaryWriter() will fail.
Rename the 'bottleneck/' directory slightly to avoid the name collision.
