python - pip install tensorflow cannot find file called client_load_reporting_filter.h

Question

I keep failing to run pip install on the tensorflow package. First it downloads the .whl file, then goes through a bunch of already satisfied requirements until it gets to installing collected packages: tensorflow, at which point here's the error I get:

ERROR: Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: 'C:\Users\Borik\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\tensorflow\include\external\com_github_grpc_grpc\src\core\ext\filters\client_channel\lb_policy\grpclb\client_load_reporting_filter.h'

I've never seen anything like this before and can't seem to find anything on the net. I'm using Windows 10 and the latest versions of Pyhton and pip.

Answer 1

I hit the same issue on Win10. Rather than renaming my filesystem, I found a good solution in this Python documentation https://docs.python.org/3/using/windows.html. Follow the instructions to update your registry for MAX_PATH, changing it from 0 to 1. This extends path from char(256) to char(32000). After this change, my 'pip install tensorflow' succeeded.
