installation help (tools.py and reduction.py syntax errors)

[olagarde]

Syntax errors (though they don't stop the install) for the following two files. I know I've missed the mako prereq, is this an artifact of that or something else I've borked?

• File "build/bdist.linux-x86_64/egg/pycuda/reduction.py", line 459: reduce_expr=f**"**{reduce_expr}"
• File "build/bdist.linux-x86_64/egg/pycuda/tools.py", line 98: file**=**self.logfile

Build/install system:

• python 2.7 (via python-2.7.5-90.el7.x86_64 from CentOS 7 Base repo)
• gcc 11.2.0 (via source build from GitHub stable 11.2.0, defaults, successful 'make check',
  built by gcc 4.8.5 via gcc-4.8.5-44.el7.x86_64 from CentOS 7 Base repo)
• pycuda 2021.1 (from here)
• no multilib, only lib64 on the local system
• local system is a private compute cluster member
  roofs is readonly, install relocated to /opt/soft/cuda/2021.2
  local system can not contact external services (no wget, curl, etc)

Steps taken:

• pycuda downloaded elsewhere, from https://files.pythonhosted.org/packages/5a/56/4682a5118a234d15aa1c8768a528aac4858c7b04d2674e18d586d3dfda04/pycuda-2021.1.tar.gz
• checksums downloaded elsewhere, from https://pypi.org/project/pycuda/#copy-hash-modal-6ab4c3e6-c78b-4d5c-aa8c-e2be3431e4c7
• ... sha256sums matched ...
• tar -xzvpf pycuda-2021.1.tar.gz
• cd pycuda-2021.1
• rm -f siteconf.py
• export PATH=/opt/soft/gcc/11.2.0/bin:$PATH
• export PYTHONPATH=/opt/soft/pycuda/2021.1/lib64/python
• mkdir -p /opt/soft/pycuda/2021.1/lib64/python
• find /opt/soft/pycuda -type d -maxdepth 4 -exec chmod 0755 {} ;
• python ./configure.py --cuda-inc-dir=/usr/include/cuda
• python ./setup.py build
• python ./setup.py install --home=/opt/soft/pycuda/2021.1

Build is successful without significant warnings, just the usual C++{std} compliance, ISO compliance, and template-depricated messages. Full output attached. Ignore the mako errors, they happened because I derped the prereqs and the build environment per Customer dictate isn't allowed to talk outside of the clusterdomain. My question is only about the syntax errors below.
install.txt

On install everything is fine until bytecompiling reduction.py and tools.py:

    ...
byte-compiling build/bdist.linux-x86_64/egg/pycuda/reduction.py to reduction.pyc
  File "build/bdist.linux-x86_64/egg/pycuda/reduction.py", line 459
    reduce_expr=f"{reduce_expr}",
                           ^
SyntaxError: invalid syntax

byte-compiling build/bdist.linux-x86_64/egg/pycuda/scan.py to scan.pyc
byte-compiling build/bdist.linux-x86_64/egg/pycuda/tools.py to tools.pyc
  File "build/bdist.linux-x86_64/egg/pycuda/tools.py", line 98
    file=self.logfile,
        ^
SyntaxError: invalid syntax
   ...

And again when unrolling the egg into the target:

...
Extracting pycuda-2021.1-py2.7-linux-x86_64.egg to /opt/soft/pycuda/2021.1/lib64/python
  File "/opt/soft/pycuda/2021.1/lib64/python/pycuda-2021.1-py2.7-linux-x86_64.egg/pycuda/reduction.py", line 459
    reduce_expr=f"{reduce_expr}",
                           ^
SyntaxError: invalid syntax

  File "/opt/soft/pycuda/2021.1/lib64/python/pycuda-2021.1-py2.7-linux-x86_64.egg/pycuda/tools.py", line 98
    file=self.logfile,
        ^
SyntaxError: invalid syntax
...

Followed by deps fetch failing because I borked the prereqs, also the build environment per Customer dictate is not allowed to talk outside of the clusterdomain (ignore this in the output, my question is about the syntax error above):

...

Python 2.7 is no longer supported by current PyCUDA. According to the package index, version 2020.1 is the last version to support 2.7: https://pypi.org/project/pycuda/2020.1/

Sorry, lost here ... that url says 2020.1 requires python ~=3.6 not 2.7, building 2020.1 or 2021.1 with 3.8.6 thows an error to the effect that it requires >3.7, and the wiki says 2021.1 requires 2.4 ... who's on first?

In hindsight I suppose the answer is obvious:  don't depend on the base os provisioning for python, it stinks.  Build a properly recent python standalone for use with pycuda, pytorch, tensorflow, etc....
